BotanyWhat sequence on the template strand of DNA corresponds to the first amino acid inserted into a protein ?

What sequence on the template strand of DNA corresponds to the first amino acid inserted into a protein ?

A
5' TAC 3'
B
5'CAT 3'
C
5'UAG 3'
D
5' AUG 3'

Solution:

The first mRNA codon to specify an amino acid is always AUG. A DNA strand with the sequence 3'TAC 5' will corresponds to the first amino acid i.e., AUG. On DNA strand A always pairs with T while on RNA strand A always pairs with U.
