Explanation:
Detailed explanation-1: -In RNA, these bases are often labeled with the letters A, U, C, and G. A set of three bases makes up a codon. The messenger RNA contains many such codons, with a series of three bases followed by three more bases, and then three more bases, and so on.
Detailed explanation-2: -There are 3 STOP codons in the genetic code-UAG, UAA, and UGA. These codons signal the end of the polypeptide chain during translation.
Detailed explanation-3: -The codon needs to be at least three bases in length. The reason for this is that there are 20 different amino acids that are used in living things, so there needs to be at least 20 different codon combinations.
