Bt cotton and Bt brinjal

Bt cotton Bt cotton is an insect-resistant transgenic crop designed to combat the bollworm. Bt cotton was created by genetically altering the cotton genome to express a microbial protein from the bacterium Bacillus thuringiensis. In short, the transgene inserted into the plant’s genome produces toxin crystals that the plant would not normally produce which, when … Read more

Biotechnology in environmental clean up process

Biotechnology in environmental clean up process Landfill Technologies Solid wastes account for an increasing proportion of the waste generated by urban societies. While a part of this volume consists of glass, plastics, and other non-biodegradable material, a considerable proportion of this is made of decomposable solid organic material, like food wastes from large poultry and … Read more

Production of Hybrid seeds and their processing techniques

Seed is the true carrier of technology. In India, three sets of institutions produce seeds:research institutions and agricultural universities; public sector seed producing corporations; andprivate sector firms including multinationals. The last decade has seen two main developmentsin seed market. One, production of quality seed has risen at a rapid rate after 2005-06. And two,public sector … Read more

Microbial infection

Microorganisms Microscopic organisms, commonly known as microorganisms or microbes, are found all around us and even inside our bodies. The category ‘Microbes’ includes a massive range of organisms including bacteria, fungi, viruses, algae, archaea and protozoa. Some of these, such as bacteria and fungi, are well known, but others such as archaea much less so. … Read more

Tissue culture and molecular markers

Tissue culture methods and applications Tissue culture refers to a method in which fragments of a tissue (plant or animal tissue) are introduced into a new, artificial environment, where they continue to function or grow. While fragments of a tissue are often used, it is important to note that entire organs are also used for … Read more

Nanotechnology and its applications

Nanotechnology and its applications The concept “Nanotechnology” was first proposed by Richard Feynman on 29th December, 1959 in his talk entitled “There’s plenty of room at the bottom” at the California Institute of Technology. Deriving its name from the Greek word “dwarf” meaning small, nanotechnology is commonly defined as the combined art of science and … Read more

Stem Cell Research

Stem Cell Research Stem cells are undifferentiated, or “blank,” cells. This means they’re capable of developing into cells that serve numerous functions in different parts of the body. Most cells in the body are differentiated cells. These cells can only serve a specific purpose in a particular organ. For example, red blood cells are specifically … Read more

Introduction and application of genetic engineering

Introduction and application of genetic engineering Genetic engineering Genetic engineering, the artificial manipulation, modification, and recombination of DNA or other nucleic acid molecules in order to modify an organism or population of organisms. The term genetic engineering initially referred to various techniques used for the modification or manipulation of organisms through the processes of heredity … Read more

Ethical, social, legal and IPR (intellectual property rights) issues related to biotechnological development.

Biotechnology through Genetic engineering has made food crops more resistant to disease, but the mere act of modification of the naturally selected food crops may actually disturb the delicate balance of biodiversity which exists in nature causing a disturbance to the natural balance. The production of GMOs has negative impacts on the natural ecosystem which … Read more
