There is only one possible sequence of amino acids when deduced from given nucleotides. But multiple nucleotides sequence can be deduced from a single amino acid sequence. Explain this phenomenon.
Answers (1)
There are 61 codons and 20 amino acids. Hargobind Khorana and Marshall Nierenberg worked on this principle. It was proposed that a codon for an amino acid is made up of 3 nucleotides. It was also seen that one codon codes for only one amino acid (unambiguous and specific).
Some amino acids are coded by more than one codon (degeneracy of codon). In simple terms, it can be said that there is only one possible sequence of amino acids when deduced from a given set of nucleotides. But multiple nucleotides sequence can be deduced from a single amino acid sequence.
