Question

what sequence of amino acids would be coded by the following set of nucleotides? aug ccu acg ugg gac
a. met his ile stop asn
b. met pro leu cys glu
c. met pro thr trp asp
d. met lys stop glu

Explanation:

Step1: Identify codons

The given nucleotide sequence AUG CCU ACG UGG GAC is read in groups of three nucleotides (codons). So the codons are AUG, CCU, ACG, UGG, GAC.

Step2: Use the codon - table

Look up each codon in the provided codon - table:

• AUG codes for Met (Methionine).
• CCU codes for Pro (Proline).
• ACG codes for Thr (Threonine).
• UGG codes for Trp (Tryptophan).
• GAC codes for Asp (Aspartic acid).

Answer:

Met Pro Thr Trp Asp
