Question

is there anyone colud help me with these questions with an explenation?

An mRNA has the following sequence

5’-AUAAGCUAUGACAGACUAUCGAUAACCAUAUACCAAG-3’

Identify the start codon and determine the amino acid sequence of the polypeptide produced.

How many different sequences of mRNA could encode a peptide with this amino acid sequence:

methionine-serine-phenylalanine-arginine

How is it possible for a gene with a mutation in its coding region to encode a protein with the same amino acid sequence as the non-mutant gene?

Explanation / Answer

AUG ACA GAC UAU CGA UAA CCA UAU ACC AAG

Methionine - threonine - aspartic acid - tyrosine - arginine - stop codon

METHIONINE (AUG); SERINE (TCT, TCC, TCA, TCG, AGT, AGC); PHENYLALANINE (TTT, TTC); ARGININE (CGT, CGC, CGA, CGG, AGA, AGG)

60 different mRNA sequences can be formed

This is due to the fact that each amino acid except for methionine has more than one codon
