CRISPR-Cas9 and Gene Editing

CRISPR-Cas9 and Gene Editing

CRISPR-Cas is a prokaryotic (loosely bacterial in non-scientific usage) immunity system that helps bacteria defend themselves from infection by bacteriophages. Bacteriophages are a kind of viruses that attack bacteria. CRISPR is a set of DNA sequences that help identify infecting bacteriophages. Cas9 is a protein that cuts the identified DNA at the required points. Together, …

Genome Editing Technologies: A New Path to Genetic Engineering

Scientists were in constant search for efficient and precise genome editing using reagents that are simple to design as well as inexpensive to generate. Developing ways to make precise, targeted changes to the genome of living cells has been a long-standing goal of biomedical researchers, who seek to understand, and hopefully cure, genetic diseases like …

Hershey Chase Experiment

Hershey-Chase Experiment

The Hershey-Chase experiments were a series of landmark experiments in the development of biology as we know it. They helped establish the nature of genetic matter. As a result, we now have a much better understanding of how genetics work and the fundamental processes involved.  Background Reproduction, and hence inheritance, is a core process of …

Immunity in Plants

We take antibiotics, vaccines, and other treatments to save ourselves from bacterial, viral, and other pathogens. Have you ever thought about how plants can save themselves? The answer to the above question is that plants have strong immune responses to cope up with bacterial and viral infections. The next question that arises in my mind …

The war against viruses

The War Against Viruses

Imagine it is the year 1985. Someone out there writing a piece of science fiction talks about how the world is troubled by a strange disease in the future. It has a plot centring around an apocalyptic event of epic proportions. Well, it’s 2020, and we live in such strange times indeed. The world is …
