New Cell Cycle/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 the mitotic phase (mitosis and cytokinesis).

Front

What occurs during interphase?

Back

Interphase is the longest phase of the cell cycle where the cell grows, duplicates its DNA, and prepares for mitosis.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, consisting of prophase, metaphase, anaphase, and telophase.

Front

What is cytokinesis?

Back

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

Front

What is a chromosome?

Back

A chromosome is a structure made of DNA and proteins that contains genetic information. Humans have 46 chromosomes.

Front

What is a chromatid?

Back

A chromatid is one half of a duplicated chromosome, which is joined to its sister chromatid by a centromere.

Front

What is a centromere?

Back

A centromere is the region of a chromosome where two sister chromatids are joined together.

Front

What is the difference between plant and animal cell cytokinesis?

Back

In plant cells, cytokinesis occurs by forming a cell plate, while in animal cells, it occurs by forming a cleavage furrow.

Front

What happens during metaphase?

Back

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

Front

What is the role of spindle fibers?

Back

Spindle fibers are structures that help separate chromosomes during cell division by pulling them to opposite poles of the cell.
