Unit 4 Cell Cycle Review

Before cells can divide, what must be copied?

• RNA

• cytoplasm

• DNA

• Cell Wall

The division of the nucleus is known as:

• Synthesis
• Mitosis
• G1
• G2

Eukaryotic cells store their genetic information(DNA) in __________.

• Chromosomes
• Centromeres
• karyotypes
• Proteins

In the S stage of interphase_______________

• the cell grows
• the nucleus divides
• the cell membrane divides
• the DNA is replicated

In the G1 stage of the cell cycle, the cell

• Grows

• Makes proteins and organelles

• Carries on normal activities

• All of the above

The cell spends most of it's life in ________________.

• mitosis
• cytokinesis
• Interphase
• None of the above

The ___________ holds the replicated sister chromatids together.

• centriole
• chromosomes
• centromere
• cycles

The structures labeled B are

• centrioles
• chromatids
• centromeres
• chromopheres

When a plant cell goes through cell division,  _____________.

• the 2 new nuclei are separated by the cell membrane pinching off.
• 4 new cells are formed
• a cell plate forms, dividing the 2 new nuclei
• None of the above

When an animal cell goes through cytokinesis,__________

• a cell plate forms dividing the 2 new nuclei.

• the cleavage furrow pinches off the 2 new cells.

• 4 new cells are formed.

• None of the above
