identify the incorrect statement ?

P) Cyclin synthesis and degradation catalysed by Skp1 cullin Fbox (SCF) ubiquitin ligase and Anaphase promoting complex (APC)

Q) a highly conserved kinase called Wee1 brings about this inhibitory phosphorylation, and a highly conserved phosphatase called Cdc25 mediates dephosphorylation.

R) CDK inhibitor proteins (CKIs) binding makes cyclin-CDK complex active.

S) CDK inhibitor proteins that regulate CDKs in plants belong to CIP/KIP family and INK4 family.
