Evolution of Brain – Where did our brains come from?

Brain in all organisms can be simply defined as a mass of nerve tissue that integrates sensory information and directs motor responses and in higher organisms, it is also the center of learning. The evolution of the brain occurred over a time scale of 3.5 billion years. It transformed from simple nerve conduction through ion channels in single-celled bacteria into a complex human brain made up of billions of cells.  Continue reading Evolution of Brain – Where did our brains come from?

Mesozoic Era – the Age of Reptiles.

The Mesozoic Era started about 225 million years prior to the present era, the amphibians were declining after a long period of supremacy among the animals and the reptiles were gradually replacing them. Many of them became very large fearsome and came to dominate the animal life practically everywhere. As a result, giant reptiles, dinosaurs, and other monstrous beasts become very abundant and spread into all habitats. For this reason, the Mesozoic era is also called the Age of Reptiles or the Age of Dinosaurs.

Sexual Reproduction – An Important Innovation of the Early Protists.​

The Kingdom Protista includes diverse kinds of predominantly water-dwelling unicellular eukaryotic microorganism. Protists, like Monerans, have an immense reproductive potential. In an optimal environment, they may reproduce several times a day. This is mainly by asexual reproduction, using the process of mitosis. However, they also reproduce sexually.

Personal Genomics: Gene Sequencing & Analysis in India.

In recent times, the people of India have been heard talking about gene sequencing, gene editing, gene sequencing, and many other similar terms. It seems like, they are now getting introduced to the idea and principle behind personal genomics. Continue reading Personal Genomics: Gene Sequencing & Analysis in India.

Free Radicals: What is their role in making us old?

From the beginning of time, people have tried to understand aging and processes associated with the biology of aging. Many scientists believe that aging results from the repetitive damage caused to our body cells. The everyday metabolic activities that usually sustain our life but also create “metabolic stress”, which over time, results in damage to our bodies. Some of these metabolic activities result in the production of radicals and which may cause harmful damage to our body cells. Continue reading Free Radicals: What is their role in making us old?

Bacterial Conjugation – A Primitive form of Sexual Reproduction.

Several Bacteria (like Escherichia Coli) exhibit a form of sexual reproduction called Bacterial Conjugation. It is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. It was discovered by Nobel Prize winners, Joshua Lederberg and Edward L. Tatum in 1946.
