The Cell Cycle
The stages of the Cell Cycle
What are Interphase and Mitotic phase (cell division)
Occurs in these cells within humans
Somatic/body cells
Structure formed between homologous pairs during synapsis
What is a tetrad/bivalent
What is to divide the cytoplasm of a parental cell into half (i.e. two daughter cells)
Duplication of the genetic material occurs here
What is the Synthesis phase (of interphase)
At the beginning of Prophase, genetic material is in this form
What is duplicated chromatin
Separates during Anaphase II
What are sister chromatids
Forms the cell plate in plant cells
What is the fusion of Golgi vesicles
The stages of Mitosis
What are prophase, prometaphase, metaphase, anaphase and telophase
Proteins that attach the spindle fibres to the centromeres of the chromosomes
Kinetochores
The reduction stage of Meiosis
What is Meiosis I (namely Anaphase I when homologs separate)
Where the cell divides
What is along its equator/metaphase plate
Proteins that are involved in the regulation of the cell cycle
What are cyclins and cyclin-dependent kinases
Forms the new membrane of a plant cell
What are golgi vesicles
Introduces genetic variation during Meiosis
Causes cleavage furrow in Animal Cells
What is contractile ring / Myosin and Actin filaments contracting
Cells that never divide such as neurons are in this phase
What is G0
Cause the cell to elongate during Anaphase
What is the lengthening of non-kinetochore microtubules
Three proteins that hold homologs together during synapsis
What is the synaptonemal complex
This would happen if cytokinesis is prohibited
What is the formation of a multinucleated cell
