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 phases: Interphase (G1, S, G2) and Mitotic phase (M).

Front

What happens during Interphase?

Back

Interphase is the phase of the cell cycle where the cell grows (G1), duplicates its DNA (S), and prepares for mitosis (G2).

Front

What occurs during Prophase?

Back

During Prophase, DNA condenses into visible chromosomes, the nuclear envelope dissolves, and centrosomes move to opposite poles of the cell.

Front

What is Telophase?

Back

Telophase is the final stage of mitosis where chromosomes unwind into diffuse DNA, the nuclear envelope reforms, and the cell begins to split.

Define Cytokinesis.

Back

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

Front

What are Sister Chromatids?

Back

Sister chromatids are identical copies of a chromosome, connected by a centromere, that are separated during Anaphase.

Front

What is the role of the centromere?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined and where the spindle fibers attach during cell division.

Front

What occurs during Anaphase?

Back

During Anaphase, the sister chromatids are pulled apart to opposite poles of the cell by the spindle fibers.

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.

Front

What happens in the S phase?

Back

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