Chapter 11 - Mitosis. Introductory Concepts. Chromatin, Chromosomes. Chromatin is a mass of uncoiled DNA and associated proteins called histones. When cell division begins, DNA coils around the proteins forming visible structures called. chromosomes. Below: Human chromosomes (female) Haploid, Diploid.
Revision notes on Mitosis for the Cambridge (CIE) IGCSE Biology syllabus, written by the Biology experts at Save My Exams.
3 wrz 2023 · Mitosis is a short period of chromosome condensation, segregation, and cytoplasmic division. The mitosis occurs in the somatic cells, and it is meant for the multiplication of cell numbers during embryogenesis and blastogenesis of plants and animals.
In biology, Mitosis is the process of chromosome segregation and nuclear division that follows replication of the genetic material in eukaryotic cells. This process assures that each daughter nucleus receives a complete copy of the organism's genetic material.

Mitosis is nuclear division during which duplicated chromosomes are segregated and distributed into daughter nuclei. Usually the cell will divide after mitosis in a process called cytokinesis in which the cytoplasm is divided and two daughter cells are formed.
Mitosis - nuclear/chemical events resulting in two daughter nuclei which have identical genetic material to each other and to the mother cell. *(Michael) I. Prophase - the first stage of mitosis. The chromosomes condense and become visible . The centrioles form and move toward opposite ends of the cell ("the poles") .
