Cell Cycle Flashcards
All the DNA in a cell = the cells _____
Genome
What carries the genetic info?
Chromosomes
What are the chromosomes before they’re chromosomes?
Chromatin
What are the replicated chromosomes?
Chromatids
Where do sister chromatids attach to each other?
Centromeres
What are the cylindrical organelles where spindles protrude from?
Centrioles
What is the microtubule organizing centre?
Centrosome
What process is the division of the nucleus?
Mitosis
What process is the division of the cytoplasm?
Cytokinesis
What does the Mitotic (M phase) consist of?
Mitosis and cytokinesis
Spindle microtubules attach to it in pro-metaphase
Kinetochores
What is Binary Fission?
Cell division in prokaryotes
Regulatory proteins:
Cyclins (CDKs)
In what phase is DNA synthesized/copied?
S phase
What phases is interphase divided into?
G1, S, G2
Between what phases does the G0 phase occur?
Between M and S
In what phase to chromosomes condense, centrosomes radiate microtubules and migrate to opposite poles?
Prophase
In what phase do the microtubules of the mitotic spindle attach to chromosomes?
Prometaphase
In what phase do the chromosomes line up at the middle of the cell?
Metaphase
In what phase do the sister chromatids separate and move to opposite sides of the cell?
Anaphase
In what phase does the nuclear envelope re-form and chromosomes condense?
Telophase
In what phase is the daughter cell completely separate and have new plasma membranes?
Cytokinesis
If cells in the process of dividing are subjected to a drug that interferes with the functioning of the spindle apparatus, at which stage will mitosis be arrested?
Interphase
