Has science finally discovered what junk DNA is and where it came from?

Question

Can this Junk DNA eventually began to group together and create more helix's besides just the double helix? If so, would we be able to use more of our brain than 10 to 15%?

Answer 1

I'm kind of confused about what you're asking exactly, many of those questions are not related to each other.

Junk DNA is already found in the double helix. It is true that much of our DNA does not code for proteins or even RNA. But we have found that they are helpful in DNA fingerprinting because of tandem/insterpersed repeats (transposons/retrotransposons) as well as Restriction fragment length polymorphisms (RFLP's)

Hope this helps :)

Answer 2

Junk DNA is that set of sequences that are remnants from evolution of our current usable DNA. These sequences no longer play any roles but, due to the enormous time lag of evolution to get rid of unneccasry "stuff" it is just there, gathering dust in the closets of our genetic material. I'm not sure that we would WANT those sequences to become activated as it would result in all sorts of strange effects and wierd looking people. ALL species have this "junk DNA" and eventually (over millions of replications) it will either produce a NEW trait or will disappear entirely.

Answer 3

If they discovered: Im not sure, although they did say a few years back that they decoded everything there is to know about our DNA.

Create more... : It is very possible.

Brain 10%-15% : That is not true :p We are using 100% of our brain ever since.

The correct is, most humans only use 10%-15% of their IQ. IQ is different from 'brain' ;)

Answer 4

definite, nicely suggested, all. yet you probably did reproduction it from a mag, definite? That suggested, Darwin and any life like scientist would welcome debate, i'm hoping. institutions of placed up-secondary preparation grant for loose communicate and debate. Many themes in technological information serve to easy up the shortcomings of medical reasoning. there are strategies in place that save faraway from puppy theories and different hindrances to know-how. even nevertheless it is not a suitable equipment. in accordance to clever layout, God is working the teach, and so it would be suitable...yet even it fairly is a undertaking to extra learn. conflict of words between scientists is information of energetic debate. Will the pro-IDers enable changing perceptions of the international...the cosmos...and nonetheless seem stable? Will they save an integrated know-how base that differences with the cases?

Answer 5

I don't think they know where it came from, maybe they know what it does on us.
