Unit 2 Biology - The Cell Cycle

Front

What is the cell cycle checkpoint that ensures DNA has been replicated correctly during S phase?

Back

G2 Checkpoint

Front

In which phase does the cell spend most of its life?

Back

Interphase

Front

What must be copied before cells can divide?

Back

DNA

Front

What happens to the cell membrane during cytokinesis in animal cells?

Back

The cell membrane pinches off to form 2 new cells.

Front

What are the individual strands on duplicated chromosomes called?

Back

Chromatids

Front

What are the main phases of the cell cycle?

Back

Interphase, Mitosis, and Cytokinesis.

Front

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

Back

To assess cell size, DNA integrity, and nutrient availability before DNA replication.

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication.

Front

What is the role of the M checkpoint?

Back

To ensure that all chromosomes are properly attached to the spindle apparatus before anaphase.

Front

What is cytokinesis?

Back

The process where the cytoplasm of a parental cell divides into two daughter cells.
