The effects of the experiment that you gave above were meant to show that you could prevent cell degredation with those chemicals and it says specifically "Near UV did not, itself, produce DNA degradation". Cell degredation causes cell death. Thats why when you go outside for long periods of time your skin gets red and starts to fall off. When exposed to certain chemicals it increases skin cell loss among other cells, they die not divide.
Ionising radiation, however, can cause damage to DNA, in many cases this leads to induced apoptosis, killing the cell to prevent the effect being copied, but not always. Sometimes it leads to effects like cancer, where cells begin to duplicate wildly. The very fact that healthy cells can become cancerous thanks to radiation exposure shows that the cell DNA can be changed. Low levels of radiation, the like of which you are exposed to all the time (background radiation) cause far less damage, but still some.
Sorry about the eye and hair thing i dumbed it down a little showing the basic model.
The problem is not "dumbing it down" the problem is that it's not relevant, because the genome remains identical in cloning.
the activation of these multiple genes and to what extent will happen during embryonic development just like it did for the carrier of the original cell. You have to look beyond just mitosis and meiosis.
And what do you think controls the activation or otherwise of a gene? That's right, other genes. And those are the same between a clone and it's original at the time the DNA sample was taken.
Alright Dolly the sheep ok remeber what i said about the genes not being watered down, that would be the same for inbred organisms except its the same organism meaning it would happen even more. Inbred species have similar problems with there heart and arthritus that were not present at such an early stage as the parents. This all of course occuring in embro developement like i said.
No, it's nothing like inbreeding. Inbreeding causes problems because there is a high likelyhood of an offspring inheriting two copies of a defective gene. Since a clone offspring is genetically identical to the original sample, this is not an issue.
