MMG 141 Chapter Notes - Chapter 2: Nuclear Membrane, Meiosis, Telophase
Document Summary
The process of cell division during which one cycle of chromosomal replication is followed by two successive cell divisions to produce four haploid cells. Duplicating of germ (egg and sperm) cells. 1 diploid cell with 46 chromosomes undergoes one round of chromosome replication, followed by two cell divisions to produce four haploid cells, containing one copy of each chromosome. Condition in which each chromosome is represent twic as a emer of a homologous pair. The condition in which each chromosome is represented once in an unpaired condition. Chromosomes condense and become visible, nuclear envelope disappears and spindle organizes. Each chromosome physically associates with its pair, each called homologous chromosomes. Chromosomes that physically associate (pair) during meiosis, possess identical gene loci. Paired homologous chromosomes line at the equator of the cell, each attached to spindle fibers from opposite poles of the cell. Members of each pair separate and move toward opposite sides of the cell.
