BIOL1006 Lecture Notes - Lecture 2: Kinetochore, Ftsz, Dna Replication
Document Summary
2 sister chromatids share common centromere after replication chromosomes counted by # of centromeres ell cycle - 5 phases. G1 primary growth phase of cell includes major part of a cell"s life for most organisms. G2 - 2nd growth phase; preparations made for separation of genomes organelles replicate, chromosomes condense, microtubules assemble interphase - collective name for g1, s, g2 phases. M (mitosis) - phase where microtubules pull sister chromatids apart divided into prophase, metaphase, anaphase, telophase. C (cytokinesis) - cytoplasm divides, forms 2 daughter cells actin acts as drawstring to pinch animal cells in 2 plate forms between dividing cells w/ cell walls embryonic cells have shortest cell cycles. 1 actin filaments slide by each other, forms cleavage furrow, eventually slices into cell"s center plant cytokinesis - creates cell plates between daughter cells. 1 fungi/protist cytokinesis - nucleus doesn"t dissolve during mitosis.
