Codons are base pair sequences that:
A
regulate the process of DNA replication
B
specify particular amino acids during protein synthesis
C
act as enzymes in metabolic reactions
D
form the double helix structure of DNA
Verified step by step guidance1
Understand what a codon is: a codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or a stop signal during protein synthesis.
Recall the central dogma of molecular biology, which describes how genetic information flows from DNA to RNA to protein.
Recognize that codons do not regulate DNA replication, act as enzymes, or form the DNA double helix structure; instead, they function during translation.
Identify that during translation, ribosomes read codons in mRNA to assemble amino acids into a polypeptide chain, thus specifying particular amino acids.
Conclude that the primary role of codons is to specify particular amino acids during protein synthesis.
