b) the mRNA transcript would be
AACGUUCGGUGA
instead of T, there is U in RNA
c) you have to look at your codon chart and see what protein every 3 nucleotides (every codon) counts for. And you will do always do this by looking at the mRNA template
AAC = Asn
GUU = Val
CGG = Arg
UGA = Stop
and that is your protein chain
