C) codon
D) nucleotide
E) codon segment

Question

Quizplus · Accepted Answer

An enhancer is a segment of DNA that determines the rate at which a protein will be synthesized by a particular structural gene. It acts as a binding site for regulatory proteins, which can either increase or decrease transcription of the gene. Ribosomes are cellular structures that carry out protein synthesis, but they do not determine the rate at which a specific protein is synthesized. Codons are sequences of three nucleotides that code for a specific amino acid during translation. Nucleotides are the building blocks of DNA, but they do not determine the rate of protein synthesis directly. Codon segment is not a well-established term in genetics.
