![]() ![]() Interphase is divided into 3shorter stages. Centrioles replicate in animal cells and it's a metabolically active stage. Each chromosome replicates to produce two sister chromatids, which remains attached each other at centromere. In this phase cell mass increases, number of cytoplasmic components doubles and DNA is duplicated. Phases of cell cycle: Interphase: The term was coined by Lundergardh in 1912, it usually longest part of the cell cycle. Howard and Pelec (1953) classified cell cycle into four stages. It can be defined as the entire sequence of events happening from the end one nuclear division to the beginning of the next. Definition of Cell cycle: The sequence of events by which a cell duplicates its genome, synthesises the other constituents of the cell and eventually divides into two daughter cells is termed cell cycle. Cytokinesis refers to the division of cytoplasm into two halves to produce two daughter cells. This term was coined by Schleicher in 1878. Types of cell division: three types cell division observed are binary fission, mitosis and meiosis Events of cell division: Karyokinesis and Cytokinesis Karyokinesis refers to division of nucleus, it is the division of chromosomes of cell into two groups which give rises to two daughter nuclei. In eukaryotes, cell division is divided into two stages ie., mitosis and meiosis. In prokaryotes, Cell division occurs by a binary fission. The cell undergoing cell division is called parental cell and one which is result of cell division is called daughter cell. HeLa Cells Immortal Cells from Henrietta Lacks that after 60+ years are still continuing to divide in a. Cell division is process of cell is an important process for growth and development of organism and repair of damaged parts of an organism. haploid half the number of body chromosomes number 25. Cell Division: The process through which new cells are formed from pre-existing cells.in other words division of chromosomes and cytoplasm of cell into two daughter cells. ![]()
