In this article we will discuss about the use of transduction of genetic mapping in viruses. Viruses are the very small particles, hence they are considered unsuitable to study inheritance. Because scorable traits are not available with them. However, some of the bacterial characters have been used for inheritance and recombination studies such as plaque morphology (large or small, fuzzy [...]
In addition to organization of DNA in prokaryotes and lower eukaryotes, in eukaryotes the DNA helix is highly organised into the well-defined DNA-protein complex termed as nucleosomes. Among the proteins the most prominent are the histones. The histones are small and basic proteins rich in amino acids such as lysine and/or arginine. Almost in all eukaryotic cells there are five [...]
In this article we will discuss about:- 1. Definition of Recombination 2. Mechanism of Recombination 3. Types. Definition of Recombination: The most important features of organisms are to adapt in the environment and to maintain their DNA sequence in the cells generation to generations with very little alterations. In long term survival of organisms depends on genetic variations, a key [...]
