Which of the following codons codes for the amino acid serine?
A
AUG
B
UCU
C
CCU
D
GCU
Verified step by step guidance1
Understand that codons are sequences of three nucleotides in mRNA that correspond to specific amino acids or stop signals during protein synthesis.
Recall that the genetic code is a set of rules used by living cells to translate information encoded within genetic material into proteins.
Identify the codons provided in the problem: AUG, UCU, CCU, and GCU.
Consult a codon table to determine which codon corresponds to the amino acid serine. A codon table maps each of the 64 possible codons to their respective amino acids.
Find that the codon 'UCU' corresponds to the amino acid serine, while the other codons correspond to different amino acids or functions.
