Question

which dna sequence and amino acid correspond to the mrna codon cgu? use complementary base pairing and this codon chart to answer the question. write the amino acid using its three - letter abbreviation. write stop for a stop codon. dna sequence
mrna codon cgu
amino acid

Explanation:

Step1: Find complementary DNA sequence

mRNA: CGU. In DNA, A pairs with T, U pairs with A, C pairs with G, G pairs with C. So DNA sequence is $\text{GCA}$.

Step2: Find matching amino acid

Locate mRNA codon CGU in the chart: first letter C, second letter G, third letter U. This corresponds to arginine (Arg).

Answer:

DNA sequence: GCA
amino acid: Arg
