Protein that protects cohesin from being degraded by separase
crossing over
Give this one a try later!
allows further exchange of genetic information between homologous
chromosomes before entering the gamete
recombination
,Give this one a try later!
the genetic process by which one chromosome breaks off and attaches to
another chromosome during reproductive cell division
chromatin remodeling
Give this one a try later!
chromatin is allowed to temporarily relax its compact structure and allow
certain parts of the DNA to be exposed to protein -binding partners
heteromorphic chromosomes
Give this one a try later!
dissimilar, such as XY in mammals that characterize one sex or the other in a
wide range of species "sex chromosomes"
mitosis
Give this one a try later!
part of eukaryotic cell division during which the cell nucleus divides
prometaphase
, Give this one a try later!
The second stage of mitosis, in which the nuclear envelope fragments and
the spindle microtubules attach to the kinetochores of the chromosomes.
