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: -A codon is a DNA or RNA sequence of three nucleotides (a trinucleotide) that forms a unit of genomic information encoding a particular amino acid or signaling the termination of protein synthesis (stop signals).

Detailed explanation-3: -The genetic code is “read” from a type of RNA called messenger RNA (mRNA). Each nucleotide triplet, called a codon, can be “read” and translated into an amino acid to be incorporated into a protein being synthesized.

Detailed explanation-4: -DNA and RNA molecules are written in a language of four nucleotides; meanwhile, the language of proteins includes 20 amino acids. Codons provide the key that allows these two languages to be translated into each other.
