  1. just because it is called junk, doesnt mean it doesnt have a function - junk food may not be good for you, but it certainly provides alot of things to your body - whether it is good or bad, its doing something - Im sure that the cells are completing some minute function that you havent thought of. : )

     

    I think this is the general gist of things.

     

    Introns are commonly efered to as junk DNA but we do now know that they are implicated in regulatory functions e.t.c. So although they dont code functional proteins. They have an effect on coding DNA which does encode functional proteins.

  2. Not all aging is due to DNA disease, however. There are genes that induce senescence (on purpose).

     

    On the other hand there are also genes that are known as longevity genes and these genes have been implicated in longevity.

     

    From my lectures on ageing i think there is a 25% heritability componont to ageing. But that is just a ballpark figure not 100% definitive
