6 Flashcards
in animal cells the centrosome has a pair of?
centrioles at the center
Duribf Interphase the centrosome?
replicate to form centrosomes
When a Chromosomes Kinetochore is captured by microtubules they?
the chromosome moves toward the pole from which the microtubules come from
What do Nonkinetochore microtubules do?
Responsible for lengthening the cell along the axis by the poles
When does a Nonkinetochore work?
Overlap across the metaphase plate
Area is reduced as motor proteins walk them away using ATP
prokaryotes reproduce by?
binary fission
bacteria have a large amount of?
large amounts of DNA that must be copied and distributed equally to 2 daughter cells
in binary fission application begins at
at the origin of replication site producing 2 origins
as the chromosome continues to replicate one origin moves?
one origin moves toward each end of the cell
when replication is complete its plasma membrane?
plasma membrane grows inward to divide the parent cell into two daughter cells
