Cloning is the process of generating a genetically identical copy of a cell or an organism. Cloning happens often in nature—for example, when a cell replicates itself asexually without any genetic alteration or recombination. Prokaryotic organisms (organisms lacking a cell nucleus) such as bacteria create genetically identical duplicates of themselves using binary fission or budding. … Read more

A biometric system is a technology which takes an individual’s physiological, behavioral, or both traits as input, analyzes it, and identifies the individual as a genuine or malicious user. Basic Components of a Biometric System Input Interface (Sensors) It is the sensing component of a biometrics system that converts human biological data into digital form. … Read more

Stem cells are a group of cells in our bodies, with capacity to self-renew and differentiate to various types of cells, thus to construct tissues and organs. In science, it is still a challenge to understand how a fertilized egg to develop germ layers and various types of cells, which further develop to multiple tissues … Read more

A concern about what affect genetically modified material could have on human health. For example, transgenic crops have been suggested to cause allergies in some people, although it is uncertain whether transgenic crops are the source of this reaction. Furthermore the antibiotic resistance genes placed in these crops has been suggested to cause resistance to … Read more

A transgenic crop is a genetically modified organism (GMO). Transgenic indicates that a transfer of genes has occurred using recombinant DNA technology. Generally a transgenic crop contains one or more genes that have been inserted artificially either from an unrelated plant or from different species altogether. Plants have been modified for many reasons over the … Read more

. In India, Ministry of Environment, Forest and Climate Change (MoEFCC) introduced the Environment (Protection) Act, 1986 as an umbrella legislation to provide a holistic framework for the protection and improvement to the environment. In connection with the use of micro-organisms and application of gene technology, the MoEFCC notified the “Rules for manufacture, use/import/export & … Read more

Biotechnology is being harnessed in various aspects of the livestock industry to hasten breed development for improved animal health and welfare, enhanced reproduction, and improved nutritional quality and safety of animal-derived foods. Artificial Insemination One of the earliest perfected technology is artificial insemination (AI) where new breeds of animals are produced through the introduction of … Read more

At present, loss of specific species, groups of species (extinction) or decrease in number of particular organisms (endangerment) are taking place in different parts of the world at a rapid pace. These losses are often manifestations of degradation or destruction in the ecosystem or habitat. DNA Banks More plant conservationists are turning to DNA technologies … Read more

. Bioremediation is a branch of biotechnology that employs the use of living organisms, like microbes and bacteria, in the removal of contaminants, pollutants, and toxins from soil, water, and other environments. Bioremediation may be used to clean up contaminated groundwater or environmental problems, such as oil spills. Bioremediation relies on stimulating the growth of … Read more

DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. If the two DNA profiles are a match, then the evidence came from that suspect. Conversely, if … Read more
