Biology 3593B Study Guide - Quiz Guide: Gene Duplication, Cytokinesis, Mitosis
Document Summary
Mitosis: start with 2n, x2, torn apart obtaining 2n, phases. Meiosis: 2n, x2, torn apart, torn apart again. Kinase- enzyme that phosporelates the proteine. ( they are dependant from cyclines) Four conditions for cell replication: reproductive signal, replication of dna ( the genetic material, segregation, cytokinesis. Prokariotes-binary fission: reproductive signal- responding to conditions in the environment, replication of dna- dna polimeraze begining with ori ending with ter, segregation- procariotic cytoskeleton helps out with the segregation, cytokinesis- begins immediately after the chromosomal duplication and segregation. G1 to s (r-restriction point)- preparation for replication xii. Prophase- the begining of mitosis ( at this phase both sister chromatines loosen up from the cohesin at the centriomere. xv. Centrosome (a pair of centrioles)- helps to put the organels in place. each centrosome forms a pole on their side of a cell. xvii. Nuclear envelope breaks down and the compacted chromosomes consisting of two chromatids attach to the kinetochore microtubules. xix.
