There are large number of debates about the utility, efficacy, advantages and disadvantages of the genetically modified crops. Each side is putting across their views in a deterministic manner. Hence genetically modified crops are referred as double […]
Gram staining is the first stage in identification of the bacteria. It differentiates the bacteria on the basis of chemical properties of their Cell Wall. Hans Christian Gram was the inventor of Gram staining. Please note that NOT all bacteria can be classified by this technique and only those bacteria which can be classified by […]
Plants get three elements viz. Carbon(C), Hydrogen (H) and Oxygen (O) from air and water.
