Meiosis Processes

Flashcards covering key stages and processes of meiosis.

Prophase I

The stage where the nuclear membrane dissolves, centrioles move to opposite poles, and spindle fibers form while homologous chromosomes intertwine.

Metaphase I

Tetrads migrate to the center of the cell and align randomly along the equator.

Anaphase I

Homologous chromosomes move to opposite poles by 'walking' across spindle fibers toward the centrioles.

Prophase II

Chromosomes condense in each haploid cell as the nuclear membrane breaks down and spindle fibers reform.

Interphase

The phase where the cell grows, duplicates its DNA, and prepares for division.

Cytokinesis

The process that produces four genetically unique haploid daughter cells, each containing a single set of chromosomes.

Telophase II

Chromatids arrive at opposite ends of the cell, uncoil, and the nuclear membrane reforms around each set of chromosomes.

Anaphase II

Sister chromatids separate and are pulled apart toward opposite poles of the cell by spindle fibers.

Metaphase II

Chromosomes line up along the equator of the cell, and spindle fibers attach to the centromeres of the sister chromatids.

Interkinesis

A brief pause after the first division of meiosis where the cell prepares for the second division without copying DNA again.

Telophase I

Chromosomes reach opposite poles of the cell, the nuclear membrane reforming around each group of chromosomes.
