Chapter 6, Problem 6LTB

Centromere between sister chromatids breaks at ________?__________of mitosis
Chromosome ____________- is the process in eukaryotes by which two sister chromatids formed as a consequence of DNA replication, or paired homologous chromosomes, separate from each other and migrate to opposite poles of the nucleus.
Mitosis
(Name the cell division phase on the line.)
DNA and centrosomes are replicated.
Name:
Chromatin condenses and supercoils to form
dense chromosomes. Since DNA was previously
replicated, the chromosomes are now present
as paired sister chromatids. Centrosomes move
to opposite sides of the nucleus and will define
the orientation of the division.
Name:
DO
