Explanation / Answer

Answer:

The given peptide is: "Alanine-Serine-Tyrosine".

In protein synthesis, the free amino group considered as 5' and free carboxyl group end considered as 3' end. Here Ala contains free amino group and the Tyr consists free carboxyl group. So given peptide is

5' Ala-Ser-Tyr 3'. Generally, protein synthesis occurred based on a 5' to 3' m RNA template strand.

Tyrosine coded two codons: UAU UAC

Serine coded by six codons: UCU, UCC, UCA, UCG, AGU, AGC

Alanine coded by four codons: GCU, GCC, GCA, GCG

2X6X4=48 possible sequences.
