Answer :
[tex]20^{250}[/tex] different 250-amino-acid-long polypeptides, each with a unique sequence, can be formed.
- If the 20 amino acids present has to arrange in any way to make a polypeptide chain than the formula for this is [tex]20^{n}[/tex] ( 20 power n). where n is the number of amino acids present in the chain. So for this case there can be 20 * 250 different proteins can be formed.
- A polypeptide is a nonstop, unbranched chain of amino acids joined by peptide bonds. To induce an amide, the peptide bond connects the carboxyl group of one amino acid to the amine group of the coming amino acid.
