Mitosis

Front

What is Mitosis?

Back

Mitosis is the process by which a single cell divides to produce two identical daughter cells, ensuring that each new cell has the same number of chromosomes as the original cell.

Front

What is Interphase?

Back

Interphase is the stage of the cell cycle where the cell spends about 90% of its time, preparing for mitosis by growing and replicating its DNA.

Front

What happens during Cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cell membrane pinches in and splits the cell into two separate daughter cells.

Front

What do cells look like at the end of Mitosis?

Back

At the end of mitosis, the two daughter cells are identical to the original cell.

Front

What occurs during Prophase?

Back

During Prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the spindle fibers begin to form.

Front

What happens during Metaphase?

Back

During Metaphase, chromosomes line up in the middle of the cell, attached to spindle fibers at their centromeres.

Front

What is Anaphase?

Back

Anaphase is the stage of mitosis where sister chromatids are pulled apart to opposite ends of the cell.

Front

What is Telophase?

Back

Telophase is the final stage of mitosis where the chromosomes reach the poles, the nuclear envelope re-forms, and the chromosomes begin to de-condense.

Front

What is the role of spindle fibers in Mitosis?

Back

Spindle fibers help separate the chromosomes during mitosis by attaching to the centromeres and pulling them apart.

Front

What is the significance of Mitosis?

Back

Mitosis is essential for growth, development, and tissue repair in multicellular organisms.
