cell cycle and cell division Flashcards
wbc and rbc are made up of
haematopoetic stem cell
e coli duration of cell cycle
20min
yeast duration for cell cycle
90 min
human cell duration for cell cycle
24 hours
cdk full form
cyclin dependent kinase
cell cycle is regulating by
cyclin, cdk
longest and least duration of cell cycle for phases
g1 and anaphase
invisible phase
s phase
synthesis of histone protein and kinetochore subunits
s phase
tubulin proteins synthesis
g2 phase
in bacteria dna replicates
before s phase
mitosis discovery in animals
flemming
mitosis discovery in animals
flemming
mitosis discovery in plant cell
stras burge
mitosis in undifferentiated germ cells
in animals
no crossing over in
mitosis
no of mitosis required
X-1
no. of mitotic generation required
2^n= X
condensin protein
in early phase condensation start
in which phase chromatids are not visible
early prophase
spireme stage
early prophase
in which phase chromatids visible
middle prophase
cohesin protein
hold two chromatids at centrosome
in which phase nuclear membrane starts disappears
middle prophase
in which phase nuclear membrane disappears
late prophase
chromosome are thickest and shortest in which phase
metaphase
best phase to study chromosome
metaphase
MPF
maturation promoting factor
APC
anaphase promoting complex
MPF activates
APC
APC inactivates
anaphase inhibitors (ex securin)
reappears of nuclear membrane nucleolus etc
telophase
