Cell Cycle and Mitosis Concepts

Front

What are the phases of the cell cycle in order?

Back

G1 (growth), S (DNA replication), G2 (prepare to divide), M (division)

Front

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

Back

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

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication takes place during the S phase.

Front

What is the role of the G2 phase in the cell cycle?

Back

The G2 phase prepares the cell for mitosis and checks for DNA damage.

Front

What is mitosis?

Back

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

Front

What does the term 'chromatin' refer to?

Back

Chromatin is the complex of DNA and proteins that forms chromosomes within the nucleus.

Front

What is the significance of the spindle apparatus during mitosis?

Back

The spindle apparatus helps separate sister chromatids during mitosis.

Front

What is the difference between mitosis and cytokinesis?

Back

Mitosis is the division of the nucleus, while cytokinesis is the division of the cytoplasm.

Front

What is a kinase?

Back

A kinase is an enzyme that catalyzes the transfer of phosphate groups to substrates, often proteins.

Front

What is a negative feedback loop?

Back

A negative feedback loop is a process that counteracts a change, helping to maintain homeostasis.
