-This codon codes for an amino acid and indicates the beginning of a coding region.

Accepted Answer

AUG is the start codon and codes for the amino acid methionine. It indicates the beginning of a coding region.

Answer: B
 UAA is a stop codon and does not code for any amino acid.

Answer: C
 UUU codes for the amino acid phenylalanine.

Answer: D
 UUA codes for the amino acid leucine.

Answer: E
 AAA codes for the amino acid lysine.

Question 9

-The anticodon AAA pairs with this codon.

Accepted Answer

The anticodon AAA pairs with the codon UUU because in RNA, adenine (A) pairs with uracil (U).
