Successful cell division requires proper chromosome movement, including accurate congression to the metaphase plate and proper segregation to spindle poles. Errors that occur in either event can cause chromosome aneuploidy in daughter cells, which may lead to cell death, genetic diseases and cancers (Matson and Stukenberg,2012, Compton, 2000). The force...
The karyotypes of five species of ranid frogs were determined
from metaphase plates of bone marrow cells. The colchicine, hypotonic-
citrate, blaze-dry technique was used to obtain the plates.
Morphometric datawere obtained from the karyotypes and compared
with other species of the genus Rana.
Like most other members of the...
The present investigation with the chromosomes of Zea mays
was conducted to determine: (1) the effects of chelating agents on the
process of cytological exchange, and (2) the effects of chelating agents
on genetic recombination.
To ascertain the influence of chelating agents on cytological
exchange, four known heterozygolis paracentric inversion...
