Multiple Choice
In the standard genetic code, what amino acid is specified by the mRNA codon CCU?
A
Leucine
B
Proline
C
Histidine
D
Serine
Verified step by step guidance1
Understand that the genetic code is read in triplets of nucleotides called codons, each specifying a particular amino acid during protein synthesis.
Identify the mRNA codon given in the problem, which is CCU.
Recall or refer to the standard genetic code table, which maps each mRNA codon to its corresponding amino acid.
Locate the codon CCU in the table; codons starting with CC (CCU, CCC, CCA, CCG) all code for the same amino acid.
Recognize that all codons beginning with CC specify the amino acid Proline.
