Mitosis Flashcards
what does mitosis result in
two daughter cells
describe the three stages of bacterial cell devision
B period - beginning of DNA replication
C period - chromosomes assemble to make a chromosome structure
D period - time between the completion of chromosome replication and completion of the cell cycle
what is prokaryotic cell devision called
binary fission
what’s the order of the distinct phases in the eukaryotic cell cycle ?
G1, S, G2, and G0
explain the G1 phase
cell carries out its function and sometimes grows
describe G2 phase
brief gap in the cell cycle where the cell prepares for mitosis and cytogenesis. getting cell ready for devision
describe G0 phase
resting phase - stopped dividing
Describe the S phase
Synthesis phase - DNA replication and chromosome duplication occur
what are kinetochore
large protein assemblies that connect chromosomes to microtubules
what happens in prophase
chromosomes condense
each chromosome is doubled from replication
spindle forms
what happens in prometaphase
breakdown of nuclear envelope
spindle enters former nuclear area
microtubules attatch
what enzyme separates the sister chromatids in Anaphase
separase
what happens in telophase
chromosomes decondense
new nuclear envelope forms
what forms the cell plate
vesicles
