How Can An Amoeba Have More DNA Than Me ?
« on: 02/08/2009 16:28:44 »
Dearest DNAologists,

As a sheepy I of course luff DNA. DNA is my all time favourite building block stuff that makes up ewe and me. I luff it...ewe luff it..we all luff it.


Also, being a sheepy I am of course extremely klevur because I have lots of DNA. Look here am I  registering to take my driving test !


Me Prior To Passing My Driving Test

Nice eh ? I do have a matching bra but it was hot so I decided to go topless.




 With all this DNA ewe'd imagine we must be very complex eh ?



The thing about DNA is that I thought that, as a sheepy I simply must have quite a lot of it..but I just found out that this humble amoeba...... .......
has about 100 times more genetic material than ewe and me !!!!!!!

eh ?...what's that all bout ?

How can a single cell organism have 100 times more DNA than me ?


Before I right my letter of complaint to the executive officer in charge of dishing out DNA I thought I'd give ewe luffley peeps a chance to explain it to me !


Hugs & shmishes


mwah mwah mwah !!!

I Dont kNow Nuffink

Genomes include junk DNA. The older the species the more time it's genome has had to accumulate junk. Amoeba have been around longer than mammals.

Ahhhh the C value paradox/enigma  :)

Non-coding DNA or 'junk DNA' is only the parts of the genome that we don't as yet know the function of, it doesn't mean it's not used.

Couple of reasonable links

http://sandwalk.blogspot.com/2007/09/genome-size-complexity-and-c-value.html

http://en.wikipedia.org/wiki/C-value_enigma

I think the safest answer is that we don't actually know why, not with any definitive proof.

If you really get the taste for it I can look up some published papers for you, but they are hard-going!  ;D

Thanks RD...so an amoeba has more junk DNA than me eh ?...hmm..well..if i eated an amoeba I'd then have more DNA than it !.. ;)
