Metaphase in Mitosis

Metaphase is the second stage of mitosis, during which chromosomes align at the cell's equatorial plane, known as the metaphase plate, and spindle fibers attach to their centromeres, preparing for separation. This alignment ensures that each daughter cell will receive an identical set of chromosomes during the subsequent anaphase.

Overview

Metaphase is a critical stage in the process of mitosis, where chromosomes align at the cell's equatorial plane. This alignment is essential for ensuring that each daughter cell receives an identical set of chromosomes, which is vital for genetic stability. The role of spindle fibers in this process...

Key Terms

Mitosis
The process of cell division that results in two identical daughter cells.

Example: Mitosis is essential for growth and repair in multicellular organisms.

Chromosome
A structure made of DNA and proteins that contains genetic information.

Example: Humans have 46 chromosomes in each somatic cell.

Chromatid
One half of a duplicated chromosome, which is joined to its sister chromatid.

Example: During metaphase, sister chromatids align at the equator.

Spindle Fibers
Protein structures that help separate chromosomes during cell division.

Example: Spindle fibers attach to the centromeres of chromosomes.

Equatorial Plane
The imaginary line where chromosomes align during metaphase.

Example: Chromosomes line up along the equatorial plane before being pulled apart.

Cell Cycle
The series of events that take place in a cell leading to its division and replication.

Example: Mitosis is a key phase of the cell cycle.
