correct ANSWERS, GRADED A+
At these checkpoints, a cyclin works with a cyclin-dependent
kinase (i.e., Cdk) to regulate the checkpoint. - ----Answers---
TRUE
The activation of both MPF and MAPK result in _________
_________ (two words) of the cytoplasm during M-phase. - ----
Answers---SETTLING DOWN
An important checkpoint regulator is at the Gap2/M-phase
transition. Here cyclin B and Cdk1 activate and form MPF which
becomes a _________ _________ (two words) and causes the DNA
to condense into _________. - ----Answers---HISTONE KINASE
& CHROMOSOMES
During mitosis, the cytoplasm of the cell is "settled down". - --
--Answers---TRUE
Gap1 of the cell cycle represents the time when the cell is
doing what it is supposed to do as part of its cell type. In other
words, that is when a liver cell is doing its function as a liver
cell. - ----Answers---TRUE
Cancer can be described as a loss of cell cycle regulation. - --
--Answers---TRUE
,After DNA synthesis (i.e., S-phase) an identical copy of the
DNA has been made and this is present in the two chromatids
when viewed as the chromosome. - ----Answers---TRUE
The synthesis/presence of cyclin is what turns on the Cdk as
the Cdk is always present but it is the cyclin that is
synthesized and degraded in cycles. - ----Answers---TRUE
The _________ begins to be destroyed at the metaphase of the
cell cycle causing the chromosomes to begin to _________. - ---
-Answers---CYCLIN B & DECONDENSE
Many chemotherapy drugs act by arresting the cell in M-phase
of the cell cycle. - ----Answers---TRUE
Cytoplasmic signal transduction controls the checkpoints of
the cell cycle. - ----Answers---TRUE

them here. - ----Answers---PLANT -- PHRAGMOPLAST
FORMATION
ANIMAL -- CONTRACTILE RING FORMATION

Answers---TRUE
List the three categories of cells in the body with regard to the

cycle
Cells that can be induced into cell cycle by injury
Cells that constantly go through cell cycle
