since it is possible to make clones can we alter the DNA by extracting the DNA and putting in new DNA that will make a super human?

Too many things can go wrong. I don't think you can just chop and change DNA like that.
-
Plus I don't think anyone has actually been cloned, well, not that I know of anyway...(https://www.thenakedscientists.com/forum/proxy.php?request=http%3A%2F%2Fbestsmileys.com%2Fthinking%2F1.gif&hash=97116900c4bbe3465843cf841da706a8)

The ethical barriers to cloning a human are almost unfathomable and insurmountable.
Even inserting a strand of DNA into a functioning genome in some way (via egg/sperm, at fertilization etc) is very hazardous - at what point do you decide to experiment? and you have to bring a child to term to really understand if you have been successful. we cannot as right-thinking people and scientists condone any line of experiments that require the carrying, birth, and infancy of other human beings as test subjects - yet this would be the only way that cloning as a technique could be improved; this, imho, is an absolute block to human cloning and complete genetic manipulation. at present [url+http://en.wikipedia.org/wiki/Gene_therapy]gene therapy[/url] as practised / as envisaged is much more viable and has fewer ethical and moral hurdles.

Ah! Doctor Frankenstein, do come in and sit down. I see you have brought your twin brother with you. Would he care for a mug of WD40?

manipulate the genes & geneswitches so 2 replace 4 limbs with 4 wings?

I read recently that cooking food in the microwave can genetically alter it. Then there's the proliferation of GM foods and seeds. Does genetically modifying our food result in second degree genetic modification of us or our offspring? So, ethical or not, aren't we already subject to DNA changes?
-
Does genetically modifying our food result in genetically modifying us or our offspring?
NO
Different nutrient availability regardless of the source may change a person's growth. But, the genes as represented by the human DNA is unaffected by the genetically modified foods.

In theory: yes, most definitely.
In practice: A lot of work needs to be done. So much even that we will not see genetically enhanced humans in our lifetime.

Has this been researched into the second and third generations yet? And who would be left on Earth to use as a control group?

The DNA in our food does not survive our intestinal tract. The DNA of our food is completely broken down, and then the basic blocks are used by our cells to create our own DNA. The little amount of food DNA that does survive the trip through our guts will end up in our toilet and will not be viable in the sewers. No need for a 2nd or 3rd generation study.

I would let them try it on me. :P

It's completely against known evidence to suggest that consuming DNA of any kind would have any affect on our own DNA. Otherwise we would have genes from chickens, cows, fish and plants in our DNA, since those things have been consumed over many, many generations back to antiquity.

Maybe true of bacteria ... http://www.the-scientist.com/?articles.view/articleNo/36108/title/Bacterial-DNA-in-Human-Genomes/
[ Definitely true of viruses (http://www.thenakedscientists.com/forum/index.php?topic=32230.msg313017#msg313017) ]

Perhaps, but I'd have to said that getting DNA modifications from microbes (those of which have an in-built ability to transfer their genes) isn't quite the same as getting DNA modifications from dead animal and plant matter.

There are some severe genetic diseases with poor prognosis.
If genetic surgery can be sucesfully demonstrated in animals, then there is a case that it should be tried in humans for whom the prospects are already grim.
I see the first human application of genetic modification being to make a "more-average" human (since this can sometimes be done with just a small genetic change throughout the body), rather than a "super" human (which would take many controlled genetic changes throughout the body).
