Cell Cycle

Front

What is the cell cycle?

Back

The cell cycle is the series of events that take place in a cell leading to its division and duplication (replication). It consists of interphase and the mitotic phase.

Front

What are the main phases of the cell cycle?

Back

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

Front

What happens during Interphase?

Back

During Interphase, the cell grows, duplicates its DNA, and prepares for mitosis. It consists of three sub-phases: G1 (growth), S (DNA synthesis), and G2 (preparation for mitosis).

Front

What is Mitosis?

Back

Mitosis is the process of nuclear division in eukaryotic cells that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is the first phase of Mitosis?

Back

The first phase of Mitosis is called Prophase, where chromatin condenses into visible chromosomes and the nuclear envelope begins to break down.

Front

How many phases are there in Mitosis?

Back

There are four phases in Mitosis: Prophase, Metaphase, Anaphase, and Telophase.

Front

What is a chromosome?

Back

A chromosome is a long, thread-like structure made of DNA and proteins that contains genetic information.

Front

What is a chromatid?

Back

A chromatid is one half of a duplicated chromosome, which is joined to its sister chromatid at the centromere.

Front

What is a centromere?

Back

A centromere is the region of a chromosome where the two sister chromatids are joined together.

Front

What is Cytokinesis?

Back

Cytokinesis is the process that follows Mitosis, where the cytoplasm of a parental cell is divided into two daughter cells.
