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…
Study notes for biology students of class-XII for the chapter Molecular Basis of Inheritance.
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…
The information stored in the DNA is decoded by the process of transcription and translation and results in the formation of the polypeptide chain or the protein, a very important and essential biomolecule in any living organism. This video provides a broad and clear picture of the process of gene expression with the help of…
Have you ever wonder if spiders can actually shoot spider web, like the one you have seen in Spider-man movies. Well, scientists have identified a spider which is capable of this. Unlike their web-spinning counterparts, ground spiders’ silk glands cannot produce the specific threads needed to anchor a web to surfaces. But they are able…
