Question

multiple choice question a codon consists of: three consecutive trna bases three consecutive rrna bases three consecutive amino acids in a protein bases three consecutive mrna bases

Explanation:

A codon is a sequence of three consecutive nucleotides (bases) in mRNA (messenger RNA) that codes for a specific amino acid or a stop signal during protein synthesis. tRNA has anticodons, rRNA is part of ribosomes, and amino acids are the building blocks of proteins, not part of codon structure. So the correct option is the one with three consecutive mRNA bases.

Answer:

D. three consecutive mRNA bases (assuming the last option is labeled D; if the original labels were different, adjust the label but the text is "three consecutive mRNA bases")
