Electron Microscopic Localization of in Situ Hybrids, made in sequence mapping at the light microscope (LM) level, there are inherent limits to resolution, notably when sequences are closely linked or when the target structure is very small. Mapping in such situations is facilitated by exploiting the resolution of the electron microscope (EM). The pri

History of Information Securityand provided a mapping scheme along each chromosome. Subsequently, a great deal of research has centered on preparing longer chromosomes with more bands visible. Chromosomes condense as they move through mitosis, and adjacent bands close up and appear to fuse. The earlier stages are longer with more

Redesigning the Molecules of Life human spermatocytes prepared by “squashing,”the only technique available to the meiotic cytogeneticist at that time. A major advance in technique took place, however, when“air-drying”of fixed spermatocytes in suspension superseded squashing (.), and this remains the preferred method for preparing h

Chromosome preparations made for SEM in the three different ways described in this chapter are illustrated in .–.. As can be seen, there is a general resemblance among chromosomes prepared by the three different techniques, but also some di
