If the sequence of bases in mRNA is U, C, A, the sequence of bases in DNA is A, G, and T.
T, G, and U.
A, C, and A.
A, G, and U.

A-G-T

Explanation:

mRNA → Polypeptide

In order to translate an mRNA sequence into a polypeptide chain, it is important to establish the correct reading frame

The mRNA transcript is organised into triplets of bases called codons, and as such three different reading frames exists

An open reading frame starts with AUG and will continue in triplets to a termination codon

A blocked reading frame may be frequently interrupted by termination codons

Once the start codon (AUG) has been located and reading frame established, the corresponding amino acid sequence can be deduced using the genetic code

Example: (mRNA)

(codons) GU AUG CAC GUG ACU UUC CUC AUG AGC UGA U
