Multiple Choice
In the context of the central dogma (translation), which amino acid is specified by the mRNA codon ACC?
A
Alanine (Ala)
B
Proline (Pro)
C
Threonine (Thr)
D
Asparagine (Asn)
Verified step by step guidance1
Recall that the central dogma of molecular biology describes the flow of genetic information from DNA to RNA to protein, where translation is the process of converting mRNA codons into amino acids.
Identify that each mRNA codon consists of three nucleotides, and each codon corresponds to a specific amino acid according to the genetic code.
Look up the mRNA codon 'ACC' in the standard genetic code table, which maps codons to their respective amino acids.
Find that the codon 'ACC' codes for the amino acid Threonine (Thr), which is one of the polar, uncharged amino acids.
Confirm that the other options (Alanine, Proline, Asparagine) correspond to different codons, so 'ACC' specifically specifies Threonine.
