The Cell Cycle Review

Front

What is the duration of the cell cycle for most animal cells?

Back

Approximately 24 hours.

Front

List the correct order of actions in the cell cycle.

Back

1. Cell grows 2. DNA replicates 3. Cell prepares for mitosis 4. Cell divides.

Front

What is the result of DNA replication?

Back

Two DNA molecules, each with one new strand and one original strand.

Front

Which strand in DNA replication is known as the leading strand?

Back

The leading strand is depicted by letter A.

Front

In DNA replication, nucleotides are added in which direction?

Back

Nucleotides are added from 5' to 3' and are said to be antiparallel.

Front

What are the main phases of the cell cycle?

Back

Interphase (G1, S, G2) and Mitosis.

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication occurs during the S phase.

Front

What is the purpose of the G1 phase in the cell cycle?

Back

The G1 phase is for cell growth and preparation for DNA synthesis.

Front

What happens during the G2 phase of the cell cycle?

Back

The cell prepares for mitosis by producing proteins and organelles.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells.
