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

. The primary intended purpose of “The DNA Technology (Use and Application) Regulation Bill, 2019” is for expanding the application of DNA-based forensic technologies to support and strengthen the justice delivery system of the country. The utility of DNA based technologies for solving crimes, and to identify missing persons, is well recognized across the world. … Read more

. Gene therapy is the treatment of disease by replacing, altering, or supplementing a gene that is absent or abnormal and whose absence or abnormality is responsible for the disease. Gene therapy may use the genetic material, DNA, itself as the means of treatment. Most, if not all, diseases have a genetic factor. The genetic … Read more

The Human Genome Project (HGP) was the international, collaborative research program whose goal was the complete mapping and understanding of all the genes of human beings. All our genes together are known as our “genome.” The main goals of the Human Genome Project were first articulated in 1988 by a special committee of the U.S. … Read more

. The recent success of gene therapy across multiple clinical trials has inspired a great deal of hope regarding the treatment of previously intractable genetic diseases. This optimism has been extended to the prospect of gene therapy for mitochondrial disorders, which are not only particularly severe but also difficult to treat. However, this hope must … Read more

. Metagenomics is the study of a collection of genetic material (genomes) from a mixed community of organisms. Metagenomics usually refers to the study of microbial communities. “Metagenomics” is the two words “meta” and “genomics”. So genomics is obtaining the DNA sequence, but meta implies that we’re doing it of many organisms together. And metagenomics … Read more

Yamanaka factors (Oct3/4, Sox2, Klf4, c-Myc) are highly expressed in embryonic stem (ES) cells, and their over-expression can induce pluripotency in both mouse and human somatic cells, indicating that these factors regulate the developmental signaling network necessary for ES cell pluripotency. However, systemic analysis of the signaling pathways regulated by Yamanaka factors has not yet … Read more
