Unit 9 - Cell Division (Biology 310)

Which of the cells in the human body have 46 chromosomes?

• Both Somatic & Gametes

• Only Somatic Cells

• Only Gametes

• Only cells produced by meiosis

A replicated chromosome is composed of:

• RNA and protein

• Two chromatids connected by a centromere

• A tetrad and two chromatins

• Only chromatin

When a cell is NOT dividing, it must be:

• in prophase

• in interphase

• dying

• in meiosis

Why do cells undergo cell division?

• growth

• repair an injury

• replacement of dead cells

• all of the answers are correct

When does DNA replication (doubling of DNA) occur?

• Prophase

• Anaphase

• Telophase

• Interphase

After a cell goes through MITOSIS, the daughter cells will immediately begin to divide again.

• True

• False

Which of the following is the correct order for MITOSIS?

• interphase, prophase, anaphase, telophase

• prophase, anaphase, telophase, metaphase

• prophase, metaphase, anaphase, telophase

• metaphase, anaphase, telophase, prophase

During prophase each of the following occurs except:

• Chromatin coiling and being visible as chromosomes.

• Breaking up and disappearance of the nuclear membrane.

• Centrioles start to move to the poles.

• Lining up of the chromosomes on the equator.

The most significant result of mitosis is that the new cells:

• Are the same size as the original cell.

• Are genetically identical to the original cell.

• Are reproductive (sex) cells.

• Have a unique mix of parent chromosomes.

Which of the following is NOT a phase of mitosis

• prophase

• interphase

• metaphase

• anaphase
