Answer 1

TAC/TTC/AAA/CCG/CGT/GGG/ATT

mRNA code can be derived as follows. In RNA instead of Thymine (T) you have Uracil (U)

mRNA string will have the complementary base pair to the DNA string

Complementary paring -

A-T here U

G-C

Therefore mRNA code is,

DNA - TAC/TTC/AAA/CCG/CGT/GGG/ATT

mRNA - AUG/AAG/UUU/GGC/GCA/CCC/UAA
