WebChromosomal mutations are very rare in nature but can be created artificially by ‘X’ rays, atomic radiation and chemicals, etc. The structural changes in chromosomes are due to breaks in chromosome, or in its cell division subunit, i.e., chromatid. Each break produces 2 ends which may then follow three different paths. (Fig.43.1). WebEvery species has its own specific number of chromosomes. For example, humans have 46 chromosomes in a typical body cell. Many species have chromosomes that come in matched pairs. For example, the 46 chromosomes in a human cell can be organized …

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… WebOct 8, 2015 · Red indicates the visible Xist RNA on an inactivated X chromosome (micrograph).
