Deoxyribonucleic acid (DNA), the genetic material for most of the living organisms, duplicates itself before the cell division by the process of cell division. This animation briefly explains the process of DNA replication, that involves enzymes like the Helicase, Primase, DNA polymerase, Exonuclease and DNA ligase. It also talks about the leading and the lagging... Continue Reading →
Ever wondered what really happens when a mosquito sits on your skin and sucks the blood out of you and occasionally leaves behind a gift for you, the virus it carries. The proboscis present in the mosquito’s mouth is a complex system of thin needles, each of which instead consists of six needle-like parts (stylets). It... Continue Reading →

DNA replication is the process by which DNA makes a copy of itself during cell division. The first step in DNA replication is to ‘unzip’ the double-helix structure of the DNA This is carried out by an enzyme called helicase which breaks the hydrogen bonds holding the complementary bases of DNA together (A with T, C with G). The separation of the... Continue Reading →
Most of us believe in the fact that we use only 10% of our brain. In an average, an adult spends 20% of the total glucose burnt to sustain the brain's energy requirement, while in children the value goes up to 50% and in infants, it is 60%. As a matter of fact the brain requires a lot... Continue Reading →
DNA or deoxyribonucleic acid is a long molecule that contains our unique genetic code. Like a recipe book, it holds the instructions for making all the proteins in our bodies. Your genome is made of a chemical called deoxyribonucleic acid, or DNA for short. DNA contains four basic building blocks or ‘bases’: adenine(A), cytosine(C), guanine (G) and thymine (T). The order, or sequence,... Continue Reading →
A genome is an organism’s complete set of genetic instructions. Each genome contains all of the information needed to build that organism and allow it to grow and develop. Our bodies are made up of millions of cells (100,000,000,000,000), each with their own complete set of instructions for making us, like a recipe book for the body.... Continue Reading →
