The correct sequence between genes and their phenotypic expression is

a) RNA-DNA-protein-trait
b) DNA-RNA-protein-trait
c) Protein-DNA-RNA-trait
d) trait-DNA-RNA-protein

I think it is either b or d but do not know if the trait is at the beginnig or end...

Once translated, the polypeptide typically undergoes substantial alteration that results in

a) excision of introns
b) addition of poly(A) tail
c) formation of peptide bonds
d) a change in its primary structure
e) the synthesis of amino acids

I think it is d but not 100% positive.
