Euthenics is a branch of applied genetics under which are studied the methods of providing, the best environmental conditions to 'nurture' to ensure complete expression of all eugenic traits in the developing children. Euthenics recommends the following methods to ensure maximum expression of genes of superior traits in the children. 1. Selection of Children with Superior Traits: The primary requirement [...]
Restriction endonuclease enzymes occur naturally in bacteria as a chemical weapon against the invading viruses. They cut both strands of DNA when certain foreign nucleotides are introduced in the cell. Endonucleases break strands of DNA at internal positions in random manner. Types of Restriction Enzymes: 1. Restriction enzyme Type I: These enzymes interact with an unmodified recognition sequence in double-stranded [...]
In this article we will discuss about the restriction maps and RFLPS. Also learn about the significance of restriction maps. The number of cuts that a restriction enzyme makes in a segment of double-stranded DNA depends on the size of that DNA, its sequence, and the number of base pairs in the recognition sequence of the particular enzyme. That is, [...]
