Protein Synthesized?

Question

A protein must be synthesized by a cell. Part of the amino acid sequence in this protein is:

-Ala-Gly-Thr-Leu-

The codons for these amino acids are:

Gly- GGC
Leu-CUA
Thr-UAU
Ala-GCA

Write the base sequence for the complete chain as given and the complimentary bases as would be found in the DNA from which it was taken.

Answer 1

G-C-A-G-G-C-U-A-U-C-U-A

C-G-T-C-C-G-T-T-T-G-T-T

The first sequence is messenger RNA, which has uracil in place of thymine in DNA.

The second sequence is the DNA from which it came,

Answer 2

5'UTR -- GCAGGCUAUCUA -- UTR3'
Here is the mRNA.

Now the DNA strand would be:
5'-CGTCCGATAGAT-3'
