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 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). There are 64 different codons: 61 specify amino acids and 3 are used as stop signals.
Detailed explanation-3: -The triplets of nitrogenous bases in DNA that code for amino acids are called codons. There are 64 codons, 61 of which code for different amino acids.
Detailed explanation-4: -The bases in mRNA are grouped into sets of three called codons.
Detailed explanation-5: -There are 3 STOP codons in the genetic code-UAG, UAA, and UGA. These codons signal the end of the polypeptide chain during translation. These codons are also known as nonsense codons or termination codons as they do not code for an amino acid.
