Question

What amino acid sequence does the following mRNA nucleotide sequence specify?

5′−AUGGCCAGCUGU−3′

Express the sequence of amino acids using the three-letter abbreviations, separated by hyphens (e.g., Met-Ser-Thr-Lys-Gly)

Answer 1

Here,

mRNA is the nucleotide sequence having many codons(made up of 3 nucleotide) which fuction is to specify the aminoacid to which codon they belong. This mRNA is the message from DNA to ribosomes to determine the amino acid sequence in protein.

Now look at the codon of above given nucleotide,

AUG:-- Methionine(Met)" start codon"

GCC:- Alanine(Ala)

AGC:-- Serine (Ser)

UGU:-- Cystein(Cys)

Now Finally have this polypeptide,

Met~Ala~Ser~Cys

That's it.
