Question

n mrna sequence and an mrna condon chart are shown.
threonine - isoleucine - serine - tryptophan
cysteine - tyrosine - arginine - threonine
serine - methionine - tyrosine - tryptophan
proline - arginine - histidine - arginine
clear all
mrna sequence: 5 ugc uac aga acc 3

Explanation:

Step1: Identify each codon

The mRNA sequence is \(5'\) UGC UAC AGA ACC \(3'\). Each group of three nucleotides is a codon. So the codons are UGC, UAC, AGA, ACC.

Step2: Use the codon chart

• For UGC: Start from the center (\(G\)), then move to \(U\), then \(C\). It codes for Cysteine.
• For UAC: Start from the center (\(A\)), then move to \(U\), then \(C\). It codes for Tyrosine.
• For AGA: Start from the center (\(A\)), then move to \(G\), then \(A\). It codes for Arginine.
• For ACC: Start from the center (\(A\)), then move to \(C\), then \(C\). It codes for Threonine.

Answer:

Cysteine - Tyrosine - Arginine - Threonine
