Cell Cycle and Mitosis

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to divide and replicate. It includes interphase (G1, S, G2) and mitotic phase (mitosis and cytokinesis).

Front

What are the main stages of mitosis?

Back

The main stages of mitosis are prophase, metaphase, anaphase, and telophase.

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 occurs during metaphase?

Back

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

Front

What is anaphase?

Back

Anaphase is the phase in mitosis where sister chromatids are pulled apart to opposite poles of the cell.

Front

What happens during telophase?

Back

During telophase, the chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm divides, resulting in two separate daughter cells.

Front

What is DNA?

Back

DNA (Deoxyribonucleic acid) is the molecule that carries genetic information in living organisms.

Front

What is the structure of DNA?

Back

DNA is structured as a double helix, consisting of two strands of nucleotides twisted around each other.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.
