S Phase
Term
In what phase is DNA copied by DNA polymerase
Definition
S Phase
Term
In what phase is the chromosomes remain bound together by proteins called cohesions
Definition
S phase
Term
Chromosomes are remained bound together, in the S phase, by a protein called:
Definition
cohesions
Term
The chromosome is bound together by cohesions until:
Definition
M- phase when the chromosomes will be separated
Term
The two phases of the cell cycle:
Definition
interphase and M phase

M phase consists of:
Definition
Mitosis (nuclear division)
Term
Is considered nuclear division
Definition
mitosis
Term

Definition
prophase
Term
During prophase, the centrosomes start to move to:

mitotic spindle
Term
During what phase does the microtubules bind to kinetochores located at chromomeres of sister chromatids
Definition
prometaphase
Term
List the order of mitosis phases:
Definition
Prophase, Prometaphase, Metaphase, Anaphase, and Telophase
Term
During what phase does the nuclear envelope beings to break down?
Definition
prometaphase
Term
During what phase does the spindle microtubles contact the condensed chromosomes?
Definition
prometaphase
Term
What allows the spindle microtubles to contact the condensed chromosomes?

condensed chromosomes
Term
During prometaphase the microtubules bind to:
Definition
kinetochores
Term
Where are the kinetochores located?
Definition
at the centromeres of sister chromatids
Term
are protein complex which assemble on the condensed chromosomes
Definition
Kinetochores
Term
Kinetochores are protein complex which:
Definition
assemble on the condensed chromosomes
Term
During what phase does the mitotic spindle gather all the chromosomes to the center of the spindle
Definition
metaphase
Term
the center of the chromosome is considered the:
Definition
equator
Term
During metaphase the mitotic spindle gathers all the chromosomes to the:
Definition
center of the spindle
Term
During what phase does the two sister chromatids in each replicated chromosome synchronously split apart?
Definition
Anaphase
Term
During Anaphase, the two sister chromatids in each replicated chromosome do what?
Definition
synchronously split apart
Term
During Anaphase, the two _______________ synchronously split apart
Definition
sister chromatids in each replicated chromosome
Term
begins abruptly with the release of the linkage that holds the sister chromatids together
Definition
Anaphase
Term
Activation of ____________ triggers the separation of sister chromatids
Definition
anaphase promoting complex (APC)
Term
After APC the chromatids are pulled to the:
Definition
Spindle pole to which it is attached
Term
during anaphase, After the chromatids are pulled to the spindle pole it segregates the sets of chromosomes to:
Definition
opposite ends of the spindle
Term
During what phase is the nuclear envelope reassemble around each of the two sets of separated chromosomes to form two nuclei
