Cell Cycle

Front

What is the purpose of cell division in organisms?

Back

Cell division is necessary for growth, repair of damaged cells, and replacement of dying cells.

Front

What regulates the cell cycle?

Back

The cell cycle is regulated by cyclins and cyclin-dependent kinases.

Front

What does NOT happen during interphase?

Back

Cell division does not occur during interphase.

Front

True or False: Normal cells grow and divide continuously.

Back

False.

Front

What are the components of a nucleotide?

Back

1) Phosphate 2) Deoxyribose Sugar 3) Nitrogen Base.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including growth and DNA replication.

Front

What are cyclins?

Back

Cyclins are proteins that regulate the cell cycle by activating cyclin-dependent kinases.

Front

What is the role of cyclin-dependent kinases (CDKs)?

Back

CDKs are enzymes that, when activated by cyclins, help to regulate the progression of the cell cycle.

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What is the G1 phase?

Back

The G1 phase is the first stage of interphase where the cell grows and synthesizes proteins necessary for DNA replication.
