During interphase, the cell's DNA is not condensed and is loosely distributed. A stain for heterochromatin (which indicates the position of chromosomes) shows this broad distribution of chromatin in a ...

Interphase is the period between cell divisions. During this time, chromosomes replicate—each DNA strand unzips into two strands while free-floating bases attach to the unzipped strands. The ...

This activity and guide has been thoughtfully designed to help you fully understand exactly what's happening at every stage of mitosis. Mitosis will produce two daughter cells which are genetically ...

After long postirradiation incubation periods, the residual frequency of prematurely condensed chromosome fragments following X-ray exposure of noncycling diploid human fibroblasts was found to be ...

This activity has been carefully designed to help you see and understand exactly what’s happening during each stage of mitosis. Mitosis will produce two daughter cells which are genetically identical ...

The killing effects of ionizing radiation on MOLT-4 cells were studied using colony formation assays, dye exclusion tests, and cell growth analysis. When MOLT-4 cells were exposed to X rays, the ...

In the process of replicating themselves, cells have another choice: do they want to make an identical copy and be left with two cells? Or do they want to make four “half-copies”, in preparation for ...
