Introduction E.coli is a Gram-negative, facultative anaerobic organism, Bacillus (shape) rod-shaped, spore forming bacterium that is commonly found in the lower gastrointestinal tract of warm-blooded organisms (endotherms). Morphologically cells are typically rod-shaped, and are about 2.0 microns (μm) long and 0.5 μm in diameter, with a cell volume of 0.6– 0.7 (μm)3. History The genera Escherichia and Salmonella diverged around 102 million years ago (credibility interval: 57–176 mya), which coincides with the divergence of their hosts: the former being found in mammals and the latter in birds and reptiles. This was followed by a split of the escherichian ancestor into…

Council of Scientific and Industrial Research(CSIR), an autonomous body, was constituted in 1942 by a resolution of the Central Legislative Assembly. The functions assigned to CSIR were: • Promotion, Guidance and Coordination of scientific and industrial research in India. • Establishment and development of institutions and assistance to departments existing institutions for specific study of problems affecting particular industries and trades. • Establishment and award of research studentships and fellowships. • Utilization of the results of the researches conducted under the auspices of the Council for the development of industries in the country. • Establishment, maintenance and management of laboratories,…

Introduction C. elegans is a nematode—a member of the phylum Nematoda. Nematodes are roundworms and threadworms, a phylum of smooth-skinned, unsegmented worms with a long cylindrical body shape tapered at the ends; includes free-living and parasitic forms both aquatic and terrestrial. C. elegans  is a non-hazardous, non-infectious, non-pathogenic, non-parasitic organism. It is small, growing to about 1 mm in length, and lives in the soil—especially rotting vegetation—in many parts of the world, where it survives by feeding on microbes such as bacteria. What makes C. elegans best model for biomedical research? Simple anatomy Easy to grow in lab Short life…

Dr. Hargobind Khorana was born on 9th January 1922 at Raipur, Punjab (now in Pakistan). Dr.Khorana was  responsible for producing the first man-made gene in his laboratory in the early seventies. This historic invention won him the Nobel Prize for Medicine in 1968 sharing it with M.W. Nuremberg and R.W. Holley for interpreting the genetic code and analyzing its function in protein synthesis. They all independently made contributions to the understanding of the genetic code and how it works in the cell. Apart from the Nobel Prize, Khorana has won many awards and honors for his achievement. Distinguished Service Award,…

Obaid Siddiqi FRS, National Research Professor at the National Centre for Biological Sciences, Tata Institute of Fundamental Research (TIFR) passed away on 26 July 2013. He is survived by his wife Asiya, sons Imran and Kalim, and daughters Yumna and Diba. Obaid Siddiqi was born in 1932 in Uttar Pradesh and received his early education at Aligarh Muslim University. He obtained his Phd from the University of Glasgow, working on microbial genetics with Guido Pontecorvo. He carried out post-doctoral research with Alan Garen at the Cold Spring Harbor Laboratory and University of Pennsylvania. This work led to the discovery of…

Introduction  D.melanogaster a fruitfly which is very famous among biologists. its great importance attracted many scientists around the world to find out more about it. Drosophila is a genus of small flies, belonging to the family Drosophilidae, whose members are often called “fruit flies”. One species of Drosophila in particular D.melanogaster has been heavily used in research in genetics and is a common model organism in developmental biology. The entire genus, however, contains about 1,500 species and is very diverse in appearance, behavior, and breeding habitat. Scientists who study Drosophila attribute the species’ diversity to its ability to be competitive…
