Detailed explanation-1: -Each group of three consecutive nucleotides in RNA is called a codon, and each codon specifies either one amino acid or a stop to the translation process.

Detailed explanation-2: -This sequence is broken into a series of three-nucleotide units known as codons (Figure 1). The three-letter nature of codons means that the four nucleotides found in mRNA-A, U, G, and C-can produce a total of 64 different combinations.

Detailed explanation-3: -A sequence of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid. Certain codons signal the start or end of translation. These are called start or stop (or termination) codons.

Detailed explanation-4: -The mRNA bases are grouped into sets of three, called codons. Each codon has a complementary set of bases, called an anticodon. Anticodons are a part of transfer RNA (tRNA) molecules.

Detailed explanation-5: -Translation is the process of reading the mRNA code in the ribosome to make a protein. Sets of three bases on the mRNA, called codons, are read in order to select the correct amino acid for building a protein.
