Biology Ch. 5 Test Prep

The 3 phases of the cell cycle are

• Interphase, mitosis, cytokinesis

• Interphase, prophase, cytokinesis

• G1, S, G2

The 3 phases of interphase are

• interphase, mitosis, cytokinesis

• G1, G2, G0

• G1, S, G2

Checkpoints are important for checking for errors or mutations. What are the 3 checkpoints?

• G1, S, G2

• nterphase, mitosis, cytokinesis

• G1, G2, metaphase

Cytokinesis is

• The division of cytoplasm

• The division of chromosomes

• The division of the DNA

The S phase is where

• cell growth happens

• DNA is replicated

• Chromatin condenses and breaks down into chromosomes

The centromere is

• Where chromatids connect together like glue

• Body cells such as lung cells and liver cells

• The chromatin that is found during interphase

Telophase is when

• chromosomes pair up and exchange DNA

• Surface area to volume ratio that is a death sentence for a cell

• Two new cells begin to form, chromosomes de-condense forming chromatin again, nuclear membrane reforms

Anaphase is when

• sister chromatids are pulled apart to opposite sides of the cell

• the chromosomes line up in the middle of the cell down the equator

• two new cells are formed that are identical

During metaphase

• The chromosomes line up in the middle of the cell down the equator

• two new cells are formed that are identical

• the cell is preparing to divide by making the nuclear membrane disappear

Which of the following is true regarding interphase?

• It is the longest phase of cell division

• DNA is not replicated here

• Anaphase takes place
