Mitosis is the process by which the somatic cells of all multicellular organisms multiply. Meiosis is a form of sexual reproduction. Features of Meiosis It results in the formation of four daughter cells in each cycle of cell division. The timing of replication and cell division is highly regulated. It G2 is the gap between the completion of DNA synthesis and the decision to divide. Strikingly, a number of the SMC family proteins, in particular the condensins and the cohesins, play similar roles in controlling sister-chromatid behavior in both meiosis and mitosis (reviewed in H aering and N asmyth 2003). Mitosis results in the production of two genetically identical diploid cells, whereas meiosis produces four genetically different haploid cells. Mitosis helps in the splitting of chromosomes during cell division and generates two new daughter cells.PDF | Meiosis is a specialised type of cell division, the principal function of which is to produce spores/gametes (sperm and eggs in mammals) that have. Regeneration and replacement of cells is another significant process of mitosis in living organisms. Alfred Cuschieri University of Malta Department of Anatomy Objectives By the end of the session the student shoud be able to: Define the meaning of chromosomes State how a kayotype is constucted. Mitosis, Meiosis and the Cell Cycle Prof. 9 Objective 15 Mitosis Meiosis Homologous chromosomes do not pair up Synapsis No genetic exchange Crossing over 49 No genetic exchange between homologous chromosomes Crossing over DNA duplication followed by 1 cell division Meiosis, on the other hand, results in four nuclei that each has ½ the chromosomes of the original cell. Students will predict what will happen to the cell if it cannot undergo mitosis and meiosis. Mitosis is the reason why human bodies can grow and repair themselves while meiosis is the process by which sexual reproduction occurs. Here are some key points regarding its significance. The process of mitosis given rise to many cells which differentiate to form tissues, organ-systems of the organsim. The resulting daughter cells are reduced in their chromosome number by half. ![]() Hence, cell division is also called cell. Explain Cell Division and Life Cycle of a Cell: Meiosis & Mitosis with Diagrams. Meiosis is the division of a germ cell into four sex cells (e.g.
