DNA is the genetic material in all except certain viruses. In Prokaryotic cells, DNA occurs in the cytoplasm and is the only component of the chromosomes. Whereas, in Eukaryotic cells, DNA is largely confined to the nucleus. Do you know, A human DNA contains 3 billion chemical letters. Yes, it is true. There are several other amazing and fun facts about DNA that we don't know.

11 Algae that are Used as Human Food.
The direct consumption of algae as human food is widely practiced around the world. A list of more than hundred species can be made which provide direct food to the human beings, especially to the coastal people of the world.
How do Auxins affect Plant growth?
Auxins are powerful plant growth hormones (or plant growth regulators) produced by plants. They are found in the shoot and root tips and promote cell division, stem and root growth. Auxins are involved in phototropism, geotropism, hydrotropism and various other developmental changes.
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.
Why are some fungi grouped under “fungi imperfecti”?
There are over 100,000 species of fungi. Some of them are one-celled like the yeasts; others are complex like mushrooms and some of them are called imperfect fungi. Fungi are the major decomposers (besides bacteria) and some parasitic forms of fungi may also cause diseases in plants and animals. Classification of Fungi: Classification of fungi is largely… Continue reading Why are some fungi grouped under “fungi imperfecti”?
Why Blue Green Algae are not included in Plantae Kingdom?
Blue Green Algae also called as Cyanobacteria are one of the most successful organisms on this planet. Initially, they were classified Plantae, but later they were moved to the Monera Kingdom.
Why is the Two-Kingdom Classification System Inadequate?
We can easily distinguish a living animal from a living plant in our surroundings. So, to keep it as simple as it was, Carolus Linnaeus classified all the organisms of the world into two Kingdoms i.e. Plantae and Animalia. But the grouping of such diverse organisms into only two kingdoms was not satisfactory to many biologists of that time.
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.
