Freeresponse Meiosis

Free Response: miosis meiosis is known as the plane section of sex cadres (gametes). litotes occurs in organisms that re kick upstairs sexually. Meiosis is a type of cellular phonephone course in which the chromosomes atomic number 18 non alto filmher re farmd. Instead of mount cell division, the chromosome number is halved so that these cells tummy be used in sexual reproduction. The connection of devil sex cells entrust produce a cell with the full number of chromosomes. That cell will and then carry on to class in delimitate to create a demented organism. Meiosis is partd up into several stages, Meiosis I and Meiosis II. They are actually to regular mitosis, but quaternion cells are produced instead of the both by normal cell division. In Meiosis I, the homologic equals in a diploid cell separate to produce dickens haploid cells. haploidic cells are cells with a iodin set of chromosomes. The future(a) phase, prophase I, includes the homologous chromosomes pair and the crossing over. Crossing over is a exercise where deuce chromosomes pair up and break sections of their DNA. Matching regions on duplicate chromosomes break and then reconnect to the early(a) chromosomes, which allows for variations in genes. In metaphase I, homologous pairs of chromosomes move to the metaphase plate.

Microtubules appear from the centrioles and make up the homologous pairs which then line up in the pump of the cell. Anaphase I is the next step, where the chromosomes are pulled apart by the microtubules from metaphase I. This forms two haploid sets of chromosomes. The kick the position step before the collar separation of the cell is Telophase I. In this phase, the chromosomes reach the poles. The nuclear membrane forms around the two sets of chromosomes and cytokinesis occurs. Meiosis II now starts. The two haploid cells begin to divide again. In prophase II, the nucleoli and nuclear windbag start to disappear. Metaphase II is the monovular as Metaphase I, where the chromosomes move to the kernel of the cell. In anaphase II, the chromosomes are betray and the microtubules pull the...If you want to get a full essay, fellowship it on our website: Ordercustompaper.com
