Cell Cycle

Front

What are sister chromatids?

Back

Sister chromatids are two identical copies of a single chromosome that are connected by a centromere.

Front

What is the cell cycle?

Back

The cell cycle is the sequence of events that a cell goes through from its formation until it divides into two daughter cells, including growth and division phases.

Front

List the phases of the cell cycle in order.

Back

G1, S, G2, Mitosis, Cytokinesis.

Front

What is chromatin?

Back

Chromatin is a complex of DNA and proteins found in the nucleus of eukaryotic cells, which condenses to form chromosomes during cell division.

Front

What is a chromatid?

Back

A chromatid is one half of a duplicated chromosome, which is formed during the S phase of the cell cycle.

Front

What is the role of the centromere?

Back

The centromere is the region of a chromosome where sister chromatids are joined together and where the spindle fibers attach during cell division.

Front

What occurs during interphase?

Back

Interphase is the 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, 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 daughter cells.

Front

What happens during the G1 phase?

Back

During the G1 phase, the cell grows and synthesizes proteins necessary for DNA replication.
