quote:Originally posted by heikkiData-"virus". (or worms etc.)Computer program-code is not basically virus. It is part of programmed technical system. Computer network (like internet) is quite big and fast technical system to made help us (humans) to conversation each other. I think that terminology is wrong if we use word virus at technical things. Technical thing is not biological living exist.
quote:1392, "venomous substance," from L. virus "poison, sap of plants, slimy liquid," probably from PIE base *weis- "to melt away, to flow," used of foul or malodorous fluids (cf. Skt. visam "poison," visah "poisonous;" Avestan vish- "poison;" L. viscum "sticky substance, birdlime;" Gk. ios "poison," ixos "mistletoe, birdlime; O.C.S. vinja "cherry;" O.Ir. fi "poison;" Welsh gwy "fluid, water," gwyar "blood").
quote:Originally posted by heikkiBiological virus. Is it good or bar or neutral living thing it's own life-purposes?Why biological virus want to live and made "childs" more viruses?
quote:But question was virus, biological virus? - Do we know what is "mind" in one virus?- Why biological virus exist? - Is it individual being thing which have some kind "brain-function" to expand viruspopulation? If not, then, how it can live?- Do we know what one virus want? How virus eat? etc. I mean what is one virus basic living needs?
quote:Originally posted by another_someoneClearly, a virus does not have a brain, in any conventional sense of the word; on the other hand, one could argue that all DNA (and RNA) contain information, and thus viruses must be capable in one way or another of processing information George
quote:Originally posted by heikkihmm? Quite good scientific conversation. If we go in the one cell, pseudonym another-someone? To new world.
quote:You wrote;DNA-RNA contain information and virus capable process this information? Of cource capable virus itself to do it because it is living thing.(Calculator is programmed by human and is technical thing, not living thing.)
quote:How?How this you called "information" is packet physical form?(hmm. Not bukee,,[^])What is this "information"? Nature round of virus, living-needs, etc?
quote:Also other question.Do we 100% scientifical know that dna-rna is the basic-place in cell where all "brain"-function is controlled?
quote:(Is dna-rna that cpu?) If it is cpu, what is that living-process system information to programmed this cpu;s? How this program-code is stored in cell, in dna-rna?
quote:What is construction of one dna-rna part when we draw it with atomic-theory?
quote:Contrary to a common misconception, the DNA is not a single molecule, but rather a pair of molecules joined by hydrogen bonds: it is organized as two complementary strands, head-to-toe, with the hydrogen bonds between them. Each strand of DNA is a chain of chemical "building blocks", called nucleotides, of which there are four types: adenine (abbreviated A), cytosine (C), guanine (G) and thymine (T). In some organisms, most notably the PBS1 phage, Uracil (U) replaces T in the organism's DNA. These allowable base components of nucleic acids can be polymerized in any order giving the molecules a high degree of uniqueness. The DNA contains the genetic information that is inherited by the offspring of an organism; this information is determined by the sequence of base pairs along its length.
quote:Originally posted by heikkiBut one biological cell? What is the process how it work? Sometimes i think my brains. My brains is cell-group. If one cell living-function is controlled 100% of dna-rna order, how brain-cell can record example this text that i memory this tomorrow when i walk.
quote:I dont know how exact views in the one cell can see with microscope so i cannot says is inside on cell any yet unknown parts which operation is unknown?Problem is perhaps also that one cell probably need other cells to live cell-group, individual thing, so then there is also important question also.How this group of cells, like our brains, understand to work? I think that dna-rna is partly like fingerprint and in the cell there is much more which take effect to control the cell-operations.
quote:No, DNA does not control 100% of how a cell behaves. The DNA controls how a cell is built, the fully constructed cell then has to interact with its environment. OK, to got back to the computer analogy, a computer is a collection of transistors; no single transistor is aware of the total functioning of a computer, it only knows how to do its own job, but the collection of all the transistors together can perform tasks that are unimaginable to any single transistor.
quote:Originally posted by heikkiHow dna control this building operation?
quote:Within a gene, the sequence of nucleotides along a DNA strand defines a messenger RNA sequence which then defines a protein, that an organism is liable to manufacture or "express" at one or several points in its life using the information of the sequence. The relationship between the nucleotide sequence and the amino-acid sequence of the protein is determined by simple cellular rules of translation, known collectively as the genetic code. The genetic code consists of three-letter 'words' (termed a codon) formed from a sequence of three nucleotides (e.g. ACT, CAG, TTT). These codons can then be translated with messenger RNA and then transfer RNA, with a codon corresponding to a particular amino acid. There are 64 possible codons (4 bases in 3 places 43) that encode 20 amino acids. Most amino acids, therefore, have more than one possible codon. There are also three 'stop' or 'nonsense' codons signifying the end of the coding region, namely the UAA, UGA and UAG codons.In many species, only a small fraction of the total sequence of the genome appears to encode protein. For example, only about 1.5% of the human genome consists of protein-coding exons. The function of the rest is a matter of speculation. It is known that certain nucleotide sequences specify affinity for DNA binding proteins, which play a wide variety of vital roles, in particular through control of replication and transcription. These sequences are frequently called regulatory sequences, and researchers assume that so far they have identified only a tiny fraction of the total that exist. "Junk DNA" represents sequences that do not yet appear to contain genes or to have a function. The reasons for the presence of so much non-coding DNA in eukaryotic genomes and the extraordinary differences in genome size ("C-value") among species represent a long-standing puzzle in DNA research known as the "C-value enigma".Some DNA sequences play structural roles in chromosomes. Telomeres and centromeres typically contain few (if any) protein-coding genes, but are important for the function and stability of chromosomes. Some genes code for "RNA genes" (see tRNA and rRNA). Some RNA genes code for transcripts that function as regulatory RNAs (see siRNA) that influence the function of other RNA molecules. The intron-exon structure of some genes (such as immunoglobin and protocadeherin genes) is important for allowing alternative splicing of pre-mRNA which allows several different proteins to be made from the same gene. Some non-coding DNA represents pseudogenes that can be used as raw material for the creation of new genes with new functions. Some non-coding DNA provided hot-spots for duplication of short DNA regions; such sequence duplication has been the major form of genetic change in the human lineage (see evidence from the Chimpanzee Genome Project). Exons interspersed with introns allows for "exon shuffling" and the creation of modified genes that might have new adaptive functions. Large amounts of non-coding DNA is probably adaptive in that it provides chromosomal regions where recombination between homologous portions of chromosomes can take place without disrupting the function of genes. Some biologists such as Stuart Kauffman have speculated that non-coding DNA may modify the rate of evolution of a species.
quote:How dna know what must done and what is time-schedule of this cell-building process?
quote:How dna know and can own that kind of skills to build itself to dna so that it has skills and information to know how build one cell? That cell where it is born, grown, and living at it's living time?
quote:What kind of stuff dna eat or drink to growth at one dna?
quote:Each vine-like molecule is a strand of DNA: a chemically linked chain of nucleotides, each of which consists of a sugar (deoxyribose), a phosphate and one of five kinds of nucleobases ("bases"). Because DNA strands are composed of these nucleotide subunits, they are polymers.The diversity of the bases means that there are five kinds of nucleotides, which are commonly referred to by the identity of their bases. These are adenine (A), thymine (T), uracil (U), cytosine (C), and guanine (G). U is rarely found in DNA except as a result of chemical degradation of C, but in some viruses, notably PBS1 phage DNA, U completely replaces the usual T in its DNA. Similarly, RNA usually contains U in place of T, but in certain RNAs such as transfer RNA, T is always found in some positions. Thus, the only true difference between DNA and RNA is the sugar, 2-deoxyribose in DNA and ribose in RNA.

It is made by rock-material handling process. And it need small matter-particle to work. Without electric transistor dont do anything.-----These 1 and 2 are totally different matter-behave area, but, can use when we try to understand what separate, technics machines and nature biological life.-----------------------
quote:Tony open this conversation question, what is the worst virus?Technical machines, like computer, term-"virus" means, program code which is done by human. Better to scientist accurate is to say, computer programmed error code, not virus. Hmm. Computer code, human programmed error code, huprog-code. Term, huprog-code, maybe new term? Virus is so common term that it is not good thing, it give wrong information to us. But, anypath, it is not my problem.
quote:Biological cell, virus? Hmm.What is virus needs?Why and how, how do know?, one virus want to reproduce itself?
quote:How virus eat?
quote:Originally posted by nilmotAll virus are evil.Ebola, Poliomyelitis, HIV...etc all pretty evil.Tom
quote:Originally posted by HadrianI can't see how something like a virus just trying to survive can be said to be evil. We all in fact owe are existences to them. Some of bacterial ancestors would kill us dead if we came in contact with them now. All the same they are life. I not saying we should not protect ourselves from them but labelling them this way is not helpful. They exist in there own universe unaware of us as we are of them most of the time. They are also likely to out-survive us too. In the bigger scheme to things I think we humans are far more destructive to the environment that we share with them. So how would you label us?
quote:Originally posted by HadrianSo I would like to state my belief that human destruction is different. We have a choice to be in this world as one with it or resist it. We can live in perfect harmony with nature like gardeners of the world. We can see to it that all we use is replaced.
quote:But we have become dazzled by our technology and fooled in to thinking that somehow we have evolved.
quote: If we were to lose every processor, every satellite and all our gadgets too we soon find out that we are no smarted then we ever were.
quote:We may have gained in some ways but we have lost so much to do it. Most people in our society would be totally unable to survive on there own wits. Tasks like finding food and shelter would be impossible for millions.
quote:As a child I remember being taught that the Roman Empire fell because they became soft and unwilling the fight. I now think the one factor was that small farmers north of Rome were bought or forced out of there land over time. When this happened Rome lost a resource of passionate men who would fight not of Rome but for their land.
quote:Human destruction is all about how we destroy are place on this planet at our peril. It is about profit over people. It is about losing our connection with the land with nature, with ourselves.
