Cell cycle and Mitosis

Front

What are spindle fibers?

Back

Spindle fibers are structures that help separate sister chromatids during cell division (mitosis) by attaching to the centromeres of chromosomes.

Front

What is the Anaphase stage in mitosis?

Back

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

Front

What is the purpose of mitosis?

Back

The purpose of mitosis is to allow cells to divide for growth, repair, and renewal.

Front

What happens during prophase of mitosis?

Back

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

Front

What are the stages of the cell cycle in order?

Back

The stages of the cell cycle in order are G1, S, G2, and M.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in two identical sets of chromosomes.

Front

What is the role of centrioles in mitosis?

Back

Centrioles help organize the spindle fibers that separate the chromosomes during mitosis.

Front

What is the difference between chromatids and chromosomes?

Back

Chromatids are identical halves of a duplicated chromosome, while chromosomes are structures that carry genetic information.

Front

What happens during telophase of mitosis?

Back

During telophase, the chromosomes uncoil into chromatin, the nuclear envelope reappears, and the spindle fibers disappear.

Front

What is cytokinesis?

Back

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