The below mentioned article provides a study note on viral genomes. Viruses are a special class of infectious agents that are so small that they can be viewed only under electron microscope. A complete "viral particle" or "virion consists of a block of genetic material (DNA or RNA) surrounded by a protein coat and, sometimes by an additional membranous envelope. [...]
In this article we will discuss about the transposable elements in the eukaryotic organisms. Transposons have been discovered in eukaryotic organisms also, e.g., controlling elements in maize, Tam1 elements in Antirrhinum majus, Ty elements in Yeast and FB elements in Drosophila. These elements can be divided into two main classes. 1. This class includes the transposable elements that are similar [...]
The following points highlight the top five techniques of chromosome banding. The techniques are: 1. C-Bands 2. G.Bands 3. Q-Bands 4. N-Bands 5. Other Techniques of Chromosome Banding. Chromosome Banding: Technique # 1. C-Bands: The technique of C-banding originated after the work of Pardue and Gall who reported that constitutive heterochromatin can be stained specifically by Giemsa-solution. Each chromosome possesses [...]
