“The Measure of Intelligence is the ability to change” Perhaps this is the reason why bacteria are able to attain resistance to variety of drugs in very short span of time. They are able to adapt the change in the environment by exchanging their genetic material by Horizontal Gene Transfer method. One such fascinating method […]

Cell cycle is a strictly regulated phenomenon that involves duplication and division of cellular material between daughter cells. It’s no secret that the regulation of cell cycle is an extremely accurate process and cell cannot afford to make any mistake. This process of maintaining the standards occur through Cell Cycle Checkpoints and Cell Cycle Regulators.

In 1951, Alma Howard (a radiobiologist) and Stephen Pelc (a physicist), conducted experiments with radioactive DNA labelling in plants and gave an outline of the cell cycle that we study today. Initially they conducted the experiment on a mouse but due to its inefficiency they used Broad bean instead. Their research introduced the G1, S,

Introduction BOD stands for Biochemical Oxygen Demand, is the amount of oxygen required for bacteria to decompose biodegradable organic matter at certain temperature for a specific period of time. It is used mainly in determination of pollution strength of water in terms of requirement of oxygen, when this wastewater is discharged into water bodies. It

Cultivation of Viruses As viruses are obligate intra-cellular parasite and they need host for their growth and survival. They dependent on host for their DNA replication, protein synthesis and multiplication. Hence, viruses cannot be grown like bacteria or other microorganisms on nutrient media. To grow or cultivate bacterial, plant and animal viruses, we need living

Viruses are defined in many ways as per different standard books but, the simplest definition of a virus is an infectious nucleic acid surrounded by Protein. Virology:- Virology is the study of viruses and virus like agents, including ( but not limited to) their taxonomy, disease producing properties, their structure, classification and evolution, their ways

Vector are small DNA molecules that are used to carry desired gene in order to insert into desired organism. Vectors are one of the most important tool in Gene cloning, Recombinant DNA Technology and Genetic Engineering. There are different types of natural and artificial vectors. In the given article, one of such natural vector and

Bacterial Growth means increase in cell size and number. As said by Jacques Lucien Monod, a Nobel Prize winner (1949) that handling microbial cultures is a fundamental methodology of microbiology and mastering different cultivation techniques should be part of every microbiologist’s craftsmanship. To conduct any kind of studies or research on microorganism, the very first

Introduction– Biofilm is a close association of cells to each other or to a specific surface forming a slimy layer. It is process where many like and unlike bacteria combine together to form a strong association which is difficult to break. This association is held tightly by extracellular polymeric substance (EPS), it acts like a
