Cell Division

Front

What is the longest phase of the cell cycle?

Back

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

Front

What phase of mitosis is characterized by the separation of sister chromatids?

Back

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

Front

What occurs during metaphase in mitosis?

Back

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

Front

What is the function of the centromere in a chromosome?

Back

The centromere is the point on a chromosome where the two sister chromatids are held together, playing a crucial role during cell division.

Front

What is cytoplasm and what is its role in a cell?

Back

Cytoplasm is a jelly-like substance found inside a cell that surrounds the organelles, providing a medium for biochemical reactions.

Front

What are the main stages of the cell cycle?

Back

The main stages of the cell cycle are interphase (G1, S, G2) and mitosis (prophase, metaphase, anaphase, telophase), followed by cytokinesis.

Front

What happens during the G1 phase of interphase?

Back

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

Front

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

Back

The S phase is significant because it is when DNA replication occurs, resulting in the duplication of chromosomes.

Front

Describe the role of spindle fibers during mitosis.

Back

Spindle fibers are responsible for separating the sister chromatids and pulling them to opposite poles of the cell during mitosis.

Front

What is the difference between mitosis and cytokinesis?

Back

Mitosis is the process of nuclear division, while cytokinesis is the division of the cytoplasm, resulting in two separate daughter cells.
