I was wondering if anyone knew exactly why a cell chooses
one gene over another in dominant genes (in some cases co-dominance).
Is there a specific nucleotide sequence in the DNA that tells if a gene/trait
is to be dominant or recessive? Such as when producing proteins,
there is a start and stop sequence telling the cell which amino acids
are appropriate for a protein. Is it a possibility that the first cell's
DNA was completely pure (dominant), and during evolution and mutations
created a recessive factor? However, some genetic diseases have dominant
hereditary (such as Epilepsy). Would it be possible to "turn off"
the nucleotides that specify Epilepsy is a dominant trait. If this
is possible, wouldn't it be possible to unlock hidden abilities
within us that are recessive? As far as I know, there are a lot of
nucleotides in DNA which are recessive (and unidentified) and have never
been "activated". Just some interesting thoughts.
Thanks for your help.
