Practice Flashcard Cell Division

Front

What organelle makes the spindle fibers needed for cell division?

Back

Centrioles

Front

If a cell has 46 chromosomes in G1 of Interphase, how many chromosomes will the new cells have after cytokinesis?

Back

46

Front

What pulls the replicated chromosomes apart during mitosis?

Back

Spindle fibers

Front

Define mitosis.

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm divides, resulting in two separate cells.

Front

What are chromatids?

Back

Chromatids are the two identical halves of a duplicated chromosome, joined together at the centromere.

Front

What is the role of centromeres in cell division?

Back

Centromeres are the regions of a chromosome where the two sister chromatids are joined and where spindle fibers attach during mitosis.

Front

What is the difference between chromatin and chromosomes?

Back

Chromatin is the relaxed form of DNA found in the nucleus during interphase, while chromosomes are the condensed form of DNA visible during cell division.

Front

What is the significance of the G1 phase in the cell cycle?

Back

The G1 phase is the first stage of interphase where the cell grows and prepares for DNA replication.

Front

What happens during the S phase of the cell cycle?

Back

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