A genetic unit that codes for the amino acid sequence of a complete plypeptide chain is most closely related to a :

What determines the number and sequence of amino acids in a polypeptide chain ?

The structure formed by the sequence of amino acids in a polypeptide chain is called :

Read the following statements. (i) One codon codes for only one amino acid. (ii) Some amino acids are coded by more than one codon. (iii) The sequence of triplet nitrogenous bases in DNA of mRNA coresponds to the amino acid sequence in the polypeptide chain. Give , suitabel terms for the characteristics of 'genetic code' as per the above statements.

[A] : Organisms that bear large number of common amino acid sequence may be con- sidered to be more closely related than to those with greatly different amino acid se- quence. [R]: The proteins are chemical finger prints of evolutionary history because they bear amino acid sequences that have changed as a re- sult of genetic change
