1.Initiator and executioner caspases share all of the following features EXCEPT that ... A.they are cysteine proteases (they have a cysteine residue at their active site). B.their inactive form is a monomer. C.they undergo cleavage during activation. D.their active form is a dimer. E.they are inhibited by IAPs. 1.Initiator and executioner caspases share all of the following features EXCEPT that ...

Explanation / Answer

Answer:-

Option -'D'-their active form is dimer.

Explanation:-

"Procaspases are the inactive precursors to caspases.

**They are activated by cleaving one or two specific aspartic acids.

**Theprocaspase is split into two subunits that form a dimer. **Two of these dimers combine to form the activated tetramer that is a caspase".
