Which codon is the code for the amino acid histidine (His)?

A. CAA
B. CAU
C. AAC
D. UAC


Sagot :

To find out which codon codes for the amino acid histidine (His), we refer to the provided mRNA codon table. The mRNA codon table maps specific three-nucleotide sequences (codons) to their corresponding amino acids.

Looking through the table:

1. The amino acid "His" (histidine) is listed in the table.
2. According to the table, histidine (His) can be identified by the following codons:

- CAU
- CAC

Given the options provided:
A. CAA
B. CAU
C. AAC
D. UAC

We see that option B, which is CAU, corresponds to histidine (His).

Therefore, the codon for the amino acid histidine (His) is:

B. CAU
