Determine the amino acid sequence that is coded for the by mRNA sequence

A mutation in the mRNA sequence changes the 6th base (read left to right) to cytosine (C). Determine the new mRNA sequence with the mutation.

4.

Determine the first four amino acids for number 3 (the mRNA sequence with the subsitution mutation)

Pitanje 5

5.

A mutation in the mRNA sequence DELETES the 6th base. Determine what the new mRNA sequence is.

6.

Determine the first four amino acids for the mutated mRNA strand in number 5.

The original mRNA sequence codes for the amino acid chain: Met-Ser-Asp-Trp. Looking back at the mutations, the subsitution (Met-Ser-Asp-Trp) and the deletion (Met-Ser-Ile-Gly), which mutation would lead to a change in the organism's physical appearance. Explain.
