Detailed explanation-1: -Codons are made up of any triplet combination of the four nitrogenous bases adenine (A), guanine (G), cytosine (C), or uracil (U). Of the 64 possible codon sequences, 61 specify the 20 amino acids that make up proteins and three are stop signals.
Detailed explanation-2: -A combination of three nitrogen bases is used as a code for each amino acid. This group of three bases is called a codon. Each codon calls for one amino acid. It takes many amino acids to form a protein.
Detailed explanation-3: -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-4: -A triplet codon is a sequence of three nitrogen bases. It is also called as a genetic code. It codes for a single amino acid.
Detailed explanation-5: -(KOH-don) 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.
