What is a sequence of three nucleotides that corresponds to a specific amino acid or stop signal during protein synthesis?

What is a sequence of three nucleotides that corresponds to a specific amino acid or stop signal during protein synthesis?

• A. Anticodon
• B. Codon
• C. Genome
• D. Chromosome

Answer: (B)

In translation, a codon is a three-nucleotide sequence in messenger RNA that specifies which amino acid to add, or signals a stop, during protein synthesis. The ribosome reads each codon and a matching tRNA brings the correct amino acid, using its anticodon to pair with the codon. This three-base code is how genetic information is turned into a protein. The anticodon is the three-nucleotide region on tRNA that pairs with the codon, not the codon itself. A genome is the organism’s entire set of genetic material, and a chromosome is a single DNA-containing structure that carries many genes; neither represents a single three-base code for an amino acid or stop signal.
