Chromosomes of a cell line of Dipodomys panamintinus (kangaroo rat). A banding and autoradiographic study.
The chromosomes of an established cell line of Dipodomys panamintinus have been characterised in terms of their C, G and Q banding patterns, and the distributions of silver grains in autoradiographs of chromosomes labelled in early or late S phase. No relationship could be established between C, G or Q banding regions of chromosomes and a particular S phase time of replication of the DNA in these banded regions. The implication of this result to the concept of heterochromatin is discussed.
