Question

What’s the correct mRNA sequence from the DNA strand: TAC GCC CGA ATC

A. ATG CCG GCU TAG

B. AUG GCC GCU UAG

C. AUG CGG GCU UAG

D. AUG CCG GCT UAG

E. ATG CCG CGT TAG

Answer 1

C. AUG CGG GCU UAG

Step-by-step explanation:

This works the same as a normal DNA strand, A=T, C=G, except for one difference. Thymine is not an mRNA base, instead it is Uracil. Therefore, if there is an A, you would typically replace it with a T, but for mRNA you will replace it with a U. Keep in mind you will still replace the T in the DNA strand with an A in the mRNA strand :)
