Question

Question 34 Not yet answered The Maturation promoting factor (MPF) is a complex formed by a cyclin dependent kinase (CDK) and a cyclin. MPF allows for the transition from G2 to M checkpoint. A mutation preventing the binding of cyclin to CDK will... Points out of 2.50 P Flag question Select one: a. increase in the phosphorylation of the cyclin targets O b. cause uncontrolled cell division and eventually a tumor c. More than one listed option are possible consequences of this event d. result in more cells arrested in the G2 to M checkpoint e. increase in the phosphorylation of the CDK targets

Answer 1

is (34) @ result in the in more cells arcrested 2 to m checkpoint. Explanation: MPE is a cyclin- cok complex which regulates the acts cell from G2 to m phase. Thes passage of by phosphoreylating substance needed fore this treansition and hence promotes and acts as check point durering cell dinsim. The MPF phosphorylation causes nucleare membreane breakdown and activate faregete to preomote chreomosome condensation case of Hence in to divide and mir mutation, the cell don't get signal is arrested at Gam phase treansition. (35) @ the rry chromosomes separate.at Anaphase I. The meiosis I deals with Reduction division where the numbere of chromosome becomes half by becomes half by maria movement of homologous chreomosomes to differeent poles. Hence xfy Chromosome separates during Anaphase j.
