Question 1

What bond do peptidases cleave?

Answer 1

Peptidases cleave amide bonds in proteins..

Don’t be fooled if it says carboxypeptidase, it will cleave the amide bond not the carboxylic acid group.

Question 2

How can multiple proteins be coded from one gene?

Answer 2

Alternate start or stop codons is one way in which multiple proteins can be produced by a single gene (they will alter TRANSLATION).

Alternative splicing of EXONS is another way multiple proteins can arise from a single gene.
