What appears to be responsible for the tighter adhesion between chromosomes seen at centromeres rather than along the chromosome arms?
A)elevated phosphorylation
B)a kinase found at the centromere that phosphorylates cohesin
C)a phosphatase found at the centromere that removes phosphate groups from cohesin if they are added
D)a phosphatase found in the chromosome arms that removes phosphate groups from cohesin
E)a phosphatase found in the chromosome arms that adds phosphate groups to cohesin

Question

Quizplus · Accepted Answer

The tighter adhesion at centromeres is due to a phosphatase that removes phosphate groups from cohesin, preventing its dissociation, unlike in the chromosome arms where cohesin is phosphorylated and removed.
