Explanation / Answer

41) check points ----------------------------j) quality control of the cell cycle

42) restriction points------------------------k) molecular switches

43) electrical synapse-----------------------g) gap junction

44) origin recognition complex------------l) real start point of the cell cycle

45) retinoblastoma---------------------------m) prevent the expression of S phase genes

46) P27------------------------------------------d) cdk inhibitor

47) cdc 25---------------------------------- f) activating phosphate from M-phase cdk  

48) kinetochore microtubules------------a) controlled by chromosome attachment to spindle

49) separase---------------------------------e) degradation of cohesion

50) cohesions--------------------------------b) hold sister chromatids together

51) metaphase- anaphase transition----c) depolymerize to mediate chromosome to pole movement

52) securin------------------------------------n) prevents the prematue separation of sister chromatids

53) g- protein -------------------------------o)-ligand dependent signalling

54) calmodulin-------------------------------i)intracellular calcium sensing

55) constitutively active pathway-------h) involved in replication licensing
