Hi Chegg,

Can you please help me answer this assignment?

Note: please only answer the question and very brief. Thanks

The genetic code is known as a \"triplet\" code, that is, a series of three nucleotides determines which amino acid is placed in the protein that is being produced. Explain why a single or double code (1- or 2- nucleotides) would not be sufficient for the genetic code.

Solution

The scientists were logically trying to crack the coding of amino acids from nucleotides to specify the placement of 20 amino acids. Since there are only four nucleotides, a code of single nucleotides would only represent four amino acids, such that A, C, G and U could be translated to encode only four amino acids. A doublet code could code for 16 amino acids (4 x 4). A triplet code could make a genetic code for 64 different combinations (4 X 4 X 4) genetic code and provide plenty of information in the DNA molecule to specify the placement of all 20 amino acids. Hence triplet codon is considered as genetic codes for amino acids and not sinlet or doublet.

Please give your review .thanks
