Concept explainers
(a)
Interpretation: The possible combinations for synthesizing dipeptides from five possible different amino acids are to be determined.
Concept introduction:
A protein is formed by the addition of amino acids in the form of a chain that is joined to each other by help of peptide bond. These proteins are formed from the code of mRNA with help from Ribosomes.
(b)
Interpretation: The possible combinations for synthesizing pentapeptides from two possible different amino acids needs to be determined. Also, it should be compared with (a) part and possible combination that gives more numbers of peptides should be selected.
Concept introduction:
A protein is formed by the addition of amino acids in the form of a chain that is joined to each other by help of peptide bond. These proteins are formed from the code of mRNA with help from Ribosomes.
