Which statement about codons and anticodons is true?
A) The codon bonds covalently with the anticodon.
B) They have the same base sequences.
C) There are 64 codons and 61 anticodons.
D) Activating enzymes link codons and anticodons.
E) At contact, the codon and the anticodon are antiparallel to each other.

Question

Quizplus · Accepted Answer

Codons and anticodons interact with each other through base pairing, but they are not covalently bonded. The base sequences of codons and anticodons are not identical, as each codon is made up of three nucleotides while each anticodon is made up of only two nucleotides. There are 64 possible codons and only 61 possible anticodons, as the third position in the codon can tolerate some variability due to the degeneracy of the genetic code. Activating enzymes are not involved in linking codons and anticodons. At contact, the codon and anticodon are antiparallel to each other, meaning they run in opposite directions.
