Lecture No. 13-15. REPRODUCTION of CAGES AND DIFFERENTIATION of CAGES
1. Reproduction of cages. Cellular cycle.
2. Division somatic and gametes. Division of gametes (meiosis).
3. Cage pathology. Factors of differentiation of cages
Reproduction of cages.Cellular cycle. Cell fission. Mitosis, amitotic division and meiosis.
Cages of live organisms breed division. Forms of reproduction of organisms are very various and difficult, but at the heart of all ways of asexual and sexual reproduction cell division lies. Characteristic of the main ways of division of eukaryotic cells: the somatic – a mitosis; the sexual – meiosis, are given in tables 6 and 7
Cell life cycle is a period from the moment of emergence of a cage to her death or before the subsequent division.
Stages of cell life cycle:
Interfaza – the period between cell divisions. Distinguish:
a) presintetichesky period (intensive synthesis of protein and growth of a cage);
b) synthetic (DNA reduplikation, synthesis of proteins of chromosomes);
c) post-synthetic (intense training to a mitosis).
