BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Hidden within the genetic code lies the “triplet code, ” a series of three nucleotides that determine a single amino acid.

Detailed explanation-2: –Three nucleotide bases make up a single codon. Each codon represents a single amino acid. Therefore, nine nucleotide bases are required to code for three amino acids.

Detailed explanation-3: -The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).

Detailed explanation-4: -Three codons are needed to specify three amino acids. Codons can be described as messengers that are located on the messenger RNA (mRNA). It is a sequence of three nucleotides that code for one specific amino acid; therefore, every three nucleotides represent one codon.

Detailed explanation-5: -If it was one DNA letter for one amino acid then you could only code for a maximum of four amino acids. Two letters in every possible combination could code for up to sixteen amino acids. Still, not enough. But three DNA letters provide more than enough combinations to code for all twenty amino acids.
