Chromosome micrograph
WebAbstract. We have used diffusive mixing and dielectrophoretic trapping to lyse Escherichia coli cells in a microfabricated environment and trap the E. coli chromosome. We characterize the conditions needed for efficient lysis of the cells, and conditions needed for the dielectrophoretic trapping of the chromatin without the trapping of ...

The metaphase chromosomes are treated with trypsin (to partially digest the chromosome) and stained with Giemsa stain. Heterochromatic regions, which tend to be rich with adenine and thymine (AT-rich) DNA and relatively gene-poor, stain more darkly in G-banding. In contrast, less condensed chromatin (Euchromatin)—which tends to be rich with guanine and cytosine (GC-rich) and more transcriptionally active—incorporates less Giemsa stain, and these regions appear as li… WebUse the chromosomes to demonstrate all the different ways they can line up on the metaphase plate. Draw a picture of each possible way of lining up. Then draw a picture of each possible gamete formed when the …
