Question

What is the difference between triplets and codons?

Answer 1

Triplet:

1. A triplet code is a sequence of three nucleotides that determines one amino acid.
2. A triplet code is the shortest combination of four nucleotides that can encode all 20 amino acids.

Codon:

1. A codon is the triplet of a set of bases (or nucleotides) in DNA that codes for an amino acid.
2. The triple base complement for a codon is called an anticodon; By convention, triplets in mRNA are called codons, and triplets in tRNA are called anticodons.
3. These codons are translated into protein sequences.

	Triplet	Codon
1.	A trinucleotide sequence or genetic code that codes for a specific amino acid in a polypeptide chain is known as a triplet code.	A codon is a three-nucleotide sequence that forms a unit of genetic code in a DNA or RNA molecule.
2.	It has no overlap and degenerates into 61 genetic codes, each of which codes for 20 amino acids.	The key that permits these two languages to be translated into each other is provided by codons.
	A triplet is a three-nucleotide sequence that is unique to an amino acid	The three-nucleotide sequence as triplets is a genetic code called codons.
3.	Example: Three, nonoverlapping, nucleotides - AAA, AAG - Lysine.	Example: Sequence AUG specified as the amino acid Methionine indicating the start of a protein.
