cell cycle review

Front

What do the 2 arrows represent?

Back

arrow 1 is interphase, arrow 2 is mitosis

Front

In what phase of the cell cycle is DNA replicated?

Back

S phase of interphase

Front

What phase is this?

Back

Anaphase

Front

How does the presence of an oncogene lead to the formation of a tumor?

Back

Cell division is unregulated.

Front

What are cancer cells likely to do because they cannot enter G0 phase?

Back

repeat the cell cycle continuously

Front

Why is DNA damage repaired before it goes into mitosis?

Back

To make sure each daughter cell is healthy and can continue growth.

Front

Where is S phase (DNA replication) occurring? Options: I, II, III, IV

Back

II

Front

DNA damage can turn off genes involved in cell-signaling pathways that regulate the cell cycle. Turning off these genes can cause less-mature cells to divide too rapidly, often leading to the development of —

Back

tumors

Front

The cellular process that enables cells to grow and develop into tissue is —

Back

Mitosis

Front

During which cellular process does telophase occur?

Back

Mitosis
