Cell Division and Reproduction Concepts

The process of cell division in a prokaryotic cell is called:

• cytokinesis.

• binary fusion.

• mitosis.

• binary fission.

Prokaryotic cell and eukaryotic cells reproduce by cell division. Regardless of the type of cell, all cells must _____ before they divide.

• make a copy of their genetic information

• reconstruct their nuclear envelope

• complete mitosis

• separate sister chromatids from one another

A cell that is not actively dividing is in what phase of the cell cycle?

• G0

• M

• S

• G2

• G1

Reproduction by mitotic cell division:

• does no require the replication of chromosomes.

• reduces the number of chromosomes by half.

• involved the formation of gametes.

• results in two daughter cells that are genetically identical.

Which cellular conditions promote progression of the cell cycle?

• the activation of CDKs

• the accumulation of cyclins

• all of these choices are correct

• binding of cyclins to CDKs

• the expression and synthesis of cyclin proteins

Replication of DNA in a eukaryote occurs during which phase of the cell cycle?

• G2 phase

• S phase

• M phase

• G1 phase

Which of the statements are true about the eukaryotic cell cycle? Select all that apply.

• The M phase consists of two events: prophase and cytokinesis.

• Interphase is typically the shortest of the two stages of the cell cycle.

• There are two stages to the cell cycle: M phase and interphase.

• Cells that have fully differentiated and no longer divide are said to be in G0 phase.

• There are three phases of interphase called: G1 phase, S phase, and G2 phase.

All of these events happen during M phase except:

• formation of the spindle.

• condensation of the chromosomes.

• synthesis of DNA.

• separation of sister chromatids.

The centrosome is:

• a region of the chromosome where sister chromatids are attached to each other.

• the microtubule organizing center for mitotic spindle.

• a region of the chromosome where microtububles attach to chromosomes during mitosis.

• a region of the chromosome where kinetochores attach.
