In this article we will discuss about:- 1. Definition of Recombinant DNA 2. History of Recombinant DNA 3. Milestones. Definition of Recombinant DNA: For centuries humans have been altering the genetic makeup of organisms by selective breeding of plant and animals. The deliberate modification in genetic material of an organism by changing the nucleic acid directly is called genetic engineering [...]
The below mentioned article provides notes on conjugation. Note # 1. Role of Surface Protein in Conjugation: Conjugation differs from transformation in the fact that in the former physical contact is established between two different strains through a conjugation tube. The genetic material from the donor cell (male) is transferred to the recipient (female) cell. There are special appendages present [...]
The following points highlight the top four applications of gene technology. The applications are: 1. Production of Pharmaceuticals 2. Diagnosis of Diseases 3. Insect Pest Control 4. Use of Genetically Engineered Microorganisms for Control of Pollution. Application # 1. Production of Pharmaceuticals: The production of medically useful human peptides and proteins (e.g. human growth hormones, insulin, somatostatin and interferon) are [...]
