WebIn mitosis, both the parent and the daughter nuclei contain the same number of chromosome sets—diploid for most plants and animals. Meiosis employs many of the same mechanisms as mitosis. However, the starting nucleus is always diploid and the nuclei that result at the end of a meiotic cell division are haploid. WebToday, mitosis is understood to involve five phases, based on the physical state of the chromosomes and spindle. These phases are prophase , prometaphase , metaphase, …
7.2 Meiosis - Concepts of Biology OpenStax
WebMitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). These … WebThe centrosome plays an important role in mitosis, acting as organization centers of microtubules and pulling apart the chromosomes when cell division happens. Prophase The first half of prophase sees the cell prepare for division by setting up certain organelles and structures. The chromosomes within the nucleus begin to condense. costa vida gage blvd richland

A regular human cell has 46 chromosomes: 44 autosomes, which come in pairs, and 2 sex chromosomes, which specify whether someone is male (usually XY) or female (usually XX). The pairs of autosomes are called "homologous chromosomes." Homologous chromosomes have all of the same genes arranged in … costa vida in clinton utah
