Mesozoic Era – the Age of Reptiles.
The Mesozoic Era spans from about 252 million years ago to about 66 million years ago that means it began roughly around the time of the end-Permian extinction. 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 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.
Like the development of the flagellum for movement, sexual reproduction in protists involving meiosis, syngamy and zygote formation appears to have been a major evolutionary innovation by the primitive protists. This innovation has made a profound effect on more complex organisms.
Personal Genomics: Gene Sequencing & Analysis in India.
In recent times, the people of India have been heard talking about gene sequencing, gene editing, gene analysis and many other similar terms. Gene or genome sequencing is a process or method of figuring out the order of DNA nucleotides or bases in a human genome. It comes under the umbrella of personal genomics.
Free Radicals: What is their role in making us old?
From the beginning of time, humans have always been concerned about aging and have tried every bit of ability to defy this process. Many of us believe that aging results from the repetitive damage caused to our body cells due to radicals produced by the everyday metabolic activities that usually sustain our life also create “metabolic stress”. But, recent studies are proving this theory of aging wrong, and are saying that so called – “evil radicals” are not so evil.
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.
