AP Biology Cell Cycle

In Somatic cell cycle

• In G1 phase DNA content is double the amount of DNA present in the origin cell

• G2 phase follows mitotic phase

• a short phase followed b along mitotic phase

• DNA replication takes place in S phase

Cell plate formation is present in

• Bacterial Cell

• Viruses

• Animal Cell

• Plant Cell

Highly coiled strand of DNA

• Chromatin

• Chromosome

• Sister Chromatid

• Centeromere

In which phase of mitosis do the sister chromatids line up on the equator of the cell?

• Prophase

• Metaphase

• Anaphase

• Telophase

During which stage of interphase does the DNA duplicate.

• M Phase

• G1 Phase

• S Phase

• G2 Phase

In the G1 stage of the cell cycle, the cell

• Grows

• Matures

• Carries on normal activities

• All of the above

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

• Cyclin concentration remains constant.

• Cyclin concentration increases during interphase and decreases during mitosis.

• Cyclin concentration decreases during interphase and increases during mitosis.

• Cyclin concentration is inversely related to MPF concentrations.

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.
