Key Concepts

Synapsis

Synapsis is the pairing of homologous chromosomes that occurs during prophase I of meiosis, not mitosis; it facilitates the exchange of genetic material (crossing over) and is not a feature of mitotic division.

Anaphase

Anaphase is a stage in mitosis during which the sister chromatids are pulled apart toward opposite poles of the cell, a key step in ensuring proper distribution of genetic material.

Centromeres

Centromeres are the specific regions on chromosomes where the sister chromatids are held together until they are separated during anaphase, ensuring each daughter cell receives an identical set of chromosomes.

Centrosomes

Centrosomes are organelles that function as the main microtubule organizing centers in cells; they play a critical role in forming the spindle apparatus that separates chromosomes during cell division.

Mitosis

Mitosis is the process of cell division where a single nucleus divides to form two genetically identical daughter nuclei, ensuring that each new cell receives the same set of chromosomes as the parent cell.
