Chapter 21 - Regulating the Eukaryotic Cell Cycle

DNA replication

________ takes place at certain origins only once until a cell goes through anaphase.

Chromosomal condensation

________ and the disassembly of G1 and G2 cells nuclear envelope is caused by discussible cyclin CDK.

Chromatids

________ and homologous chromosomes have at least one recombination occur between them.

Kinase

________ regulates the phosphorylation of condensin complexes powered by MPF.

MPF activity

________ falling also helps with the removal of inhibition of the myosin light chain, which lets the cleavage furrow form into cytokinesis.

Mitogens

________ which are peptide growth factors make mammalian cells that are cultured proliferate.

Heterodimers

________ are formed with CDK when Clb3 and Clb4 are expressed during the S phase.

extract sources

Eggs and early embryos of amphibians and invertebrates when fertilized provide ________ that help in biochemical studies for the cell cycles events.

MPF

________ catalyzed phosphorylation of lamins A, B, and C along with inner nuclear proteins and nucleoporins occurs early in mitosis.

Cdc20

________ directs APC to polyubiquitinated securin at the onset of anaphase.

Protein phosphates

________ are able to remove regulatory phosphates such as:

fission yeast S pombe

The ________ gets encoded a cyclin- dependent protein kinase which is associated with a mitotic cyclin, which results in a mitotic cyclin CDK heterodimer.

Cell cycle

________ proteins that work in mitotically dividing cells also work in meiosis undergoing cells.

Mitotic cyclin activity

________ is needed for protein kinase MPF.

DNA replication

________ in the S phase forms sister chromatids that are linked at the centromere because of cohesion complexes.

MPF

________ activities rise and fall is result by concomitant synthesis and mitotic cycle degradation.
