Chapter 11: Cell cycle
mitosis
earlier stage
Chromatin condensation gathered into a chromosome
The center body moves to the poles and forms a spindle
premetaphase
Degrading of nuclear fiber layer, promoting the disintegration of nuclear membrane
Spinners connect the chromosomes to form a mitotic
Chromosal arrangement to equatorial plate
metaphase
Chromosomes arranged on equatorial plates
anaphase
Sister chromatids moves to poles
telephase
Chromosome Spyrolysis
Nuclear kernel Reassembly
Nuclear membrane formation
Subcell nucleus Formation
Formation of two subcells
maiosis
first division
Early stage Ⅰ
Fine line: Chromatin initiation
amphitene
Homologous chromosome pairing to form tetrents
Forof a association Complex
Thick line period: Cross-exchange between non-sister chromatids
diplotene
Long duration; to association, but crossover
Cross terminal: cross movement towards the end of the chromosome
diakinesis
Homologous chromosome condensation into short rods
Cross-termination continues
Nuclear kernel disappear, nuclear membrane disintegration, spindle formation
The quartet starts moving towards the equatorial plate
metaphase Ⅰ
Qutrents arranged on equatorial plates
anaphase Ⅰ
Homologous chromosomes separate from each other and move to the cell poles
Non-homologous chromosomes enter the poles in a free combination of
telephase Ⅰ
Chromosome Spyrolysis
Nuclear kernel and membrane reappear to form two cell nuclei
Formation of two subcells
second division
Early stage Ⅱ
Basically the same as the terminal subtraction cells
metaphase Ⅱ
Chromosomes arranged on equatorial plates
anaphase Ⅱ
Sister chromatiers separated and moved to the cell poles
telephase Ⅱ
Form two subcells (haploid)
regulatory mechanism
cyclin
classify
G1 cyclin
Phase S cyclin
S cyclin
Phase M cyclin
architecture
Cyclin Box
Mediated cyclin and cyclin-dependent kinase formation complex
Broken ring box
Made of nine amino acid residues that mediate the rapid degradation of the cyclin A, B
PEST sequence
Mediates the degradation of the cyclin C, D, E
Cyclin-dependent Kinase (CDK)
A class of protein kinases that must bind to cyclin to have kinase activity
Participate in regulating the cell cycle by phosphorylating cell cycle-related proteins
CDK kinase activity inhibitors
mechanism of action
cell type
Continuous divided cells
Highdifferentiated cells (terminal differentiated cells)
G0 cells
Usually dormancy, requiring special stimulation for cell division, eg: liver and renal cells
oncepct
The process experienced by a cell growing from the end of one cell division to the end of the next division
interkinesis
Phase G1 (early stage in DNA synthesis)
Phase S (DNA synthetic period)
Phase G2 (late in DNA synthesis)
nuclear fission
Start with the presence of chromosomes until the two subnuclei
cytokinesis
Formation of shrinkage ring: composed of microfilament
Contraction ring hanging out
