Question

Select ALL that are true of EVERY member of the cyclin family.

a) Are kinases
b) Has endogenous GTPase
c) Concentration cycles once per cell cycle
d) Concentration cycles in M-phase

Answer 1

Every member of the cyclin family has endogenous GTPase activity and their concentration cycles once per cell cycle. However, they do not cycle specifically in M-phase.

Step-by-step explanation:

Every member of the cyclin family is not a) a kinase, but they have endogenous GTPase (b) activity. Furthermore, their concentration cycles once per cell cycle (c) and they do not cycle specifically in M-phase (d).
