Biology: Cell Cycle and Mitosis

Front

What is the role of cyclins in the cell cycle?

Back

Cyclins are proteins that regulate the progression of the cell cycle by activating cyclin-dependent kinases (CDKs).

Front

Which stage of the cell cycle is the longest?

Back

Interphase is the longest stage of the cell cycle, where the cell grows and prepares for division.

Front

During which stage does the nucleus divide?

Back

The nucleus divides during mitosis.

What occurs during prophase?

Back

During prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

What is a tumor?

Back

A tumor is an abnormal mass of tissue that forms when cells grow and divide uncontrollably.

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and M phase (Mitosis and Cytokinesis).

Front

What happens during the S phase of Interphase?

Back

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

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm divides, resulting in two separate daughter cells.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis produces four genetically diverse gametes.

What is the function of spindle fibers?

Back

Spindle fibers help separate chromosomes during cell division by attaching to the centromeres and pulling them apart.
