Cell Division

Front

What are cyclins?

Back

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

Front

What is a normal cell cycle?

Back

A normal cell cycle is a series of phases (G1, S, G2, and M) that a cell goes through to grow and divide properly, involving regulated processes.

Front

What is an abnormal cell cycle?

Back

An abnormal cell cycle refers to uncontrolled cell division, which can lead to conditions such as cancer.

Front

What happens during interphase?

Back

During interphase, the cell grows, duplicates its DNA, and prepares for mitosis.

Front

What occurs in metaphase?

Back

In metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to their centromeres.

Front

What happens during telophase?

Back

During telophase, the nucleolus reappears, and the chromosomes begin to de-condense, leading to the formation of two distinct nuclei.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What are the phases of mitosis?

Back

The phases of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What is the role of spindle fibers?

Back

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

Front

What is the significance of the G1 phase?

Back

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