Coronavirus Precautions

1. Washing hands frequently Coronaviruses contain genetic information (single stranded RNA) inside fat-based covering known as a viral envelope. When they interact with soap, this coating of fat will be destroyed by the soap molecules. Thus, virus can no longer infect the host organism. 2. Stay at home Stay at home# Best advice that can […]

Why are cells important?

Body is made up of many complicated chemicals and water. The water together with these chemicals are assembled into cells. Cells are important in separating extracellular matrix (water present outside the cell) from cytosol (water present inside the cell). They are structural unit as they form the structure of the organism. They are functional unit […]

Coronavirus- Introduction

A coronavirus disease, also known as COVID-19, where 19 specifies the year 2019 and COVID stands for coronavirus disease. It was first identified in Wuhan, China. It is also known as SARS-CoV-2 as it is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV is the strain of virus that causes contagious respiratory disease […]

Five forces of evolution

Evolution means changes in gene or allele frequencies within a population over generations and these changes lead to different genetic makeup of species. Five forces of evolution includes: 1. Natural Selection 2. Genetic Drift 3. Mutations 4. Gene Flow. 5. Non-Random Mating 1. Evolution which is due to natural selection depends on fitness of individuals […]

Micrococcal Nuclease ( MNase)

Micrococcal Nuclease ( MNase) is an endonuclease and exonuclease. It cleaves RNA or DNA sequences randomly. Endonuclease cleaves phosphodiester bonds within polynucleotide chain and exonuclease cleaves the phosphodiester bonds at the ends of polynucleotide chain. Micrococcal nuclease has exonuclease and endonuclease activity both. It cleaves 5′-phosphodiester bonds against RNA and DNA mainly at AT or […]
