I just read that only 2% of human DNA codes for proteins although 80% of DNA is expressed (which I take to mean transcribes).
This leaves me wondering what one would find, as one works one's way down a DNA thread?
If a gene is a portion of DNA which codes for a mRNA, what does the rest do, if anything?
Could someone give an explanation of what is going on in a DNA thread apart from coding for RNA
My previous idea was that DNA was triplet sequences of base pairs, that code for particular amino acids (via MRSA) polypeptides and proteins; with stop codons seperating processes.
A gene, to me, was a length of DNA containing Exons and introns, exons being (potentially) translatable into protiens and introns only reaching the trascription stage.
It seems this is way too simplistic?
