Chapter 10 test Flashcards
chromatid
each side of a chromosome (worm)
chromatin
material of chromosomes
DNA wrapped around proteins
centromere
belt of chromosome
centrioles
controls the spindles
spindle fibers
pull apart chromatids
reasons for cell division
to create more efficient smaller cells
as cell size increases?
less efficient
volume grows faster than surface area
interphase
90% of a cells life
not part of mitosis
G1
cell growing
S
DNA replication
G2
preparing for mitosis
prophase
nuclear membrane disintegrates
chromosomes condense
spindle forms
metaphase
chromosomes line up across the cell
centromeres connect with spindles
anaphase
chromosomes separate
chromosomes move to opposite side of the cell
telophase
chromosomes spread onto chromatin
nuclei form around each cluster
spindle breaks
