What is Southern Blotting? How it is used to identify Specific DNA Sequences?

Southern Blotting is an elegant technique that can be used to identify the locations of genes and other DNA sequences on restriction fragments separated by gel electrophoresis. This technique is named after the Edwin Southern (1975) who developed it. Continue reading What is Southern Blotting? How it is used to identify Specific DNA Sequences?

What are the different Causes of Antibiotic Resistance?

Antibiotic Resistance is a term that appears to be like some super terms used in some science fiction movies. But this term is something from which we should be afraid of because antibiotic resistance and spread of drug-resistant pathogens are one of the most serious and dangerous threats to public health in this 21st century. Continue reading What are the different Causes of Antibiotic Resistance?

What is Eutrophication? What are its Causes & Effects?

The phenomenon of a sudden increase in the organic and inorganic nutrient supply in an aquatic environment is referred to as Eutrophication. These nutrients are basically nitrogen and phosphorous, and they favour overgrowth of algae and grazing bacteria, which then results in oxygen depletion. Continue reading What is Eutrophication? What are its Causes & Effects?

How do cells in Embryo get their Roles to Play?

The cells of an embryo get their roles when they are capable of differentiating autonomously in a neutral environment such as petri dish or test tube. (the environment is neutral with respect to the development pathway.) This process of giving different roles to embryonic cells is called Cell Specification. Continue reading How do cells in Embryo get their Roles to Play?
