Cell Cycle All questions

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 (M phase, which includes prophase, metaphase, anaphase, and telophase).

Front

What occurs during G1 phase of interphase?

Back

During G1 phase, the cell grows and synthesizes proteins necessary for DNA replication.

Front

What occurs during S phase of interphase?

Back

During S phase, DNA replication occurs, resulting in the duplication of chromosomes.

Front

What occurs during G2 phase of interphase?

Back

During G2 phase, the cell continues to grow and prepares for mitosis by producing proteins and organelles.

Front

What is mitosis?

Back

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

Front

What happens during prophase?

Back

During prophase, chromosomes condense and become visible, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What happens during metaphase?

Back

During metaphase, chromosomes line up at the cell's equator, and spindle fibers attach to the centromeres of the chromosomes.

Front

What happens during anaphase?

Back

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

Front

What happens during telophase?

Back

During telophase, the chromosomes de-condense, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.
