CHROMOSOMES AT THE CENTER

A

METAPHASES

37
Q

IF THE CHROMOSOMES IS IN THIS POSITION , ANAPHASES COMMENSES

38
Q

SISTER CHROMATIDS ARE TIGHTLY PAIRED DUE TO THE CENTROMERE AND PROTEIN COHESIN

39
Q

SISTER CHROMATIDS SEPARATE FROM EACH OTHER

40
Q

SPINDLE FIBER BEGIN TO SHORTEN TO OULL THE SISTER CHROMATIDS AWAY FROM EACH OTHER TOWARD THE OPPOSITE ENDS OF THE CELL

41
Q

CHROMATIDS TO OPPOSITE SIDES

42
Q

COMPLETE SET OF IDENTICAL CHROMOSOMES ARE NOW POSITIONED AT EACH POLE OF THE CELL

43
Q

REBUILD THE NUCLEAR MEMBRANE AROUND EACH SET OF CHROMOSOMES

44

Q

THE ORDERLY PROGRAMMED OF CELL DEATH OR SUICIDE BY UNCONTROLLED CELL DEATH IS CALLED

54
Q

THIS IS THE BODYS WAY TO GET RID OF ALL THE CELL THAT ARE NO LONGER FUNCTIONING

55
Q

IF THERE IS UNCONTROLLED CELL DIVISION IF MAY PRODUCED ABNORMALITIES IN THE CELL

56
Q

THIS CONDITION WHEREIN A GROUP OF CELLS IS CHARACTERIZED BY UNCONTROLLED AND ABNORMAL CELL DIVISION

A

GAMETOGENESIS

70
Q

MEIOSIS IS THE PRIMARY EVENT IN THIS PROCESS

A

GAMETOGENESIS

71
Q
