Biological Cell Division Processes Quiz

Interphase is the phase where cells grow, carry out normal functions, and replicate their DNA.

Mitosis is the process of cell division that results in two identical daughter cells with the same genetic material as the parent cell.

The spindle apparatus is responsible for separating sister chromatids during cell division.

Metaphase I is the stage where homologous chromosomes align at the cell's equator in meiosis.

The kinetochore is a protein structure that anchors spindle fibers to the centromere, facilitating chromosome movement during cell division.

Helicase is the enzyme that separates the DNA strands by breaking hydrogen bonds, allowing for replication.

Anaphase is the stage where sister chromatids are pulled apart towards opposite ends of the cell.

The G1 checkpoint assesses DNA integrity before committing to the S phase of the cell cycle.

The centrosome is crucial for spindle fiber organization and proper cell division.

Crossing over, the exchange of genetic material, takes place during Prophase I of meiosis.

Cytokinesis completes the cell division process by physically separating the cell into two distinct daughter cells.

Apoptosis is programmed cell death and not a form of cell division.

G1 phase is dedicated to cell growth and preparation for the upcoming division.

The G2 checkpoint ensures that DNA is undamaged before entering the mitotic phase.

Both mitosis and meiosis occur in somatic cells, contributing to growth, development, and reproduction.

Apoptosis plays a crucial role in eliminating unwanted or damaged cells, maintaining tissue homeostasis in multicellular organisms.
