In mitosis , the two resulting cells are

identical to the starting cell and identical to each other.

different from the starting cell and identical to each other.

different from the starting cell and different from each other.

identical to the starting cell and different from each other.

Which of the following shows the correct sequence of the cell cycle?

G1->S->G2->mitosis->cytokinesis

Mitosis-> G1->S->G2->cytokinesis

S->G1-> G2-> mitosis-> cytokinesis

cytokinesis->mitosis->G1->S->G2

Which of the following shows the correct sequence of the cell cycle?

G1->S->G2->mitosis->cytokinesis

Mitosis-> G1->S->G2->cytokinesis

S->G1-> G2-> mitosis-> cytokinesis

cytokinesis->mitosis->G1->S->G2

What is the role of the spindle during mitosis?

It helps separate the chromosomes.

It breaks down the nuclear membrane.

How does mitosis in plant cells differ from mitosis in animal cells?

plant cells go through the process in reverse

plant cells go through two rounds of mitosis while animal cells just do one

Crossing over involves:

alignment of homologous chromosomes

Why do cells such as neurons divide very rarely?

They no longer have active nuclei

they can no longer break down cyclins

What two components make an active MPF

cyclin and a cyclin-dependent kinase

a growth factor and a mitotic factor

Cells from cancerous tumors usually have an unusual number of chromosomes, and unusual looking chromosomes. What could explain this?

cell cycle check points are not in place

cancer cells are arrested in the S phase

transformation introduces new chromosomes to cells

Why do we need meiosis?

To halve the number of chromosomes going into sex cells

To double the number of chromosomes going into sex cells

To triple the number of chromosomes going into sex cells

To not change the number of chromosomes going into sex cells

Why do cells such as neurons divide very rarely?

They no longer have active nuclei

they can no longer break down cyclins

When a plant cell goes through cell division, _____________.

a cell plate forms, dividing the 2 new nuclei

the 2 new nuclei are separated by the cell membrane pinching off.

What is the role of protein kinases?

add phosphate groups and energy to activate enzymes

remove phosphate groups to deactivate enzymes

Which of these may be assessed by various proteins during a "checkpoint"? CHECK ALL THAT APPLY

Ensure that DNA has been replicated properly

Ensure that spindle fibers have attached to all centromeres before cell division

Ensure that all chromosomes have lined up in the center of the cell before sister chromatids separate

Which description is true about cell cycle regulation?

Changing concentrations of cyclin result in binding to Cdk

Changing concentrations of Cdk result in binding to cyclin

MPF complex formation decreases with increased Cdk levels

MPF complex formation decreases with increased cyclin levels

How does the concentration of cyclin dependent kinases (Cdk) change as the cell proceeds through the cell cycle?

Cdk concentration remains constant.

Cdk concentration increases during interphase and decreases during mitosis.

Cdk concentration decreases during interphase and increases during mitosis.

Cdk concentration correlates directly with MPF concentration.

How does the concentration of cyclin change as a cell goes through the cell cycle?

Cyclin concentration increases during interphase and decreases during mitosis.

Cyclin concentration remains constant.

Cyclin concentration decreases during interphase and increases during mitosis.

Cyclin concentration is inversely related to MPF concentrations.

Once a cell completes mitosis, what happens to MPF?

the cyclin component of MPF is degraded

the Cdk component of MPF is degraded

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

In order for genetic information to be transferred into daughter cells.

In order for the cell to be able to increase in size.

In order for the DNA to be contained in the nucleus.

In order for the cell to re-order the DNA sequencing in the new cells.
