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 (G1, S, G2) and the mitotic phase (M).

Front

What are the main stages of the cell cycle?

Back

The main stages of the cell cycle are Interphase (G1, S, G2) and the Mitotic phase (M).

Front

What happens during Interphase?

Back

During Interphase, the cell grows (G1), duplicates its DNA (S), and prepares for mitosis (G2).

Front

What is mitosis?

Back

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

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical cells, while meiosis results in four genetically diverse cells with half the chromosome number.

Front

What is crossing over and when does it occur?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during Prophase I of meiosis.

Front

What is a tetrad?

Back

A tetrad is a structure containing four chromatids that forms during Prophase I of meiosis when homologous chromosomes pair up.

Front

What occurs during Anaphase I of meiosis?

Back

During Anaphase I, homologous chromosomes are pulled apart to opposite poles of the cell.

Front

What occurs during Anaphase II of meiosis?

Back

During Anaphase II, sister chromatids are pulled apart to opposite poles of the cell.
