Answer 2

Answer:

Codon the sequence of three bases that codes for a specific amino acid.

Explanation:

• Codons, which are groupings of three nucleotides, are read by cells to decode mRNA. Here are a few characteristics of codons:
• The majority of codons define an amino acid.
• A protein's termination codons are three "stop" codons.
• The beginning of a protein is marked by one "start" codon, AUG, which also codes for the amino acid methionine.
• During translation, an mRNA's codons are read starting at a start codon and continuing until they reach a stop codon. The order of amino acids in a protein, from the N-terminus (methionine) to the C-terminus, is determined by mRNA codons, which are read from 5' to 3'.
• The genetic code refers to the entire set of interactions between codons and amino acids (or stop signals).

Hence, option (C) is correct.
