Industrial microbiology is the use of microorganisms like bacteria, fungi, and yeast for producing useful materials on a large scale. It is the process where these microbes are grown under controlled conditions so that they can convert raw materials into different products. It is the process mainly linked with fermentation and other bioconversion methods, and … Read more
What is Biological Clocks? Biological clocks are the internal timing system present in living organisms, and it is the process by which rhythmic changes occur in a regular pattern. It is an endogenous mechanism that runs for about 24 hours, and this rhythmic behaviour is referred to as circadian rhythm. The rhythm continues even in … Read more
Nylander’s test is a qualitative test that is used for detecting reducing sugars. It is the process where the reducing sugar is heated with an alkaline solution containing bismuth salt, and the reaction is controlled by the components present in the reagent. The reagent is made of bismuth nitrate or bismuth subnitrate, potassium sodium tartrate, … Read more
Okazaki fragment is the short segment of DNA that is synthesized on the lagging strand during DNA replication. It is formed because the DNA polymerase can extend the new strand only in the 5’–3’ direction, so the strand that is oriented in the 3’–5’ direction is produced in a discontinuous manner. It is initiated by … Read more
The Picric Acid Test is used to detect the presence of reducing sugars in a solution. It is a general chemical test and it is based on the reduction of picric acid under alkaline condition. Picric acid is a yellow crystalline compound (2,4,6-trinitrophenol) and it is converted into picramic acid when it reacts with a … Read more
What is Lane-Eynon Method? Principle of Lane-Eynon Method The method based on reduction of cupric ions (Cu²⁺) to cuprous oxide (Cu₂O) by the reducing sugars in alkaline condition. In the reaction, CuSO₄ from Fehling A and alkaline tartrate from Fehling B react to form a deep blue cupric–tartrate complex, which remain stable in hot solution … Read more
Post-transcriptional modification is a set of biological processes common to most eukaryotic cells by which an primary RNA transcript is chemically altered following transcription from a gene to produce a mature, functional RNA molecule that can then leave the nucleus and perform any of a variety of different functions in the cell.
What is Analytical balance? What is Triple beam balance? Difference Between Analytical Balance Vs Triple Beam Balance 1. Precision – Analytical balance gives very high precision (up to 0.0001 g) while triple beam balance only measure till 0.01 g, so less sensitive comparatively. 2. Power Source – Analytical balance mostly works on electric / electronic … Read more
What is Biogeny (Formation of Primitive Life)? 1. Formation of nucleic acids and nucleoproteins The formation of nucleic acids and nucleoproteins considered as one of the key transition in Biogeny where information molecules begin to store and transmit life instructions. It started after Chemogeny produced small organic monomers like nucleobases, sugars, phosphates, etc. Prebiotic synthesis … Read more
What is Polarizing Microscope? Principles of Polarized Light Microscopes The Light Path and Image Formation of Polarized Light Microscopes Parts of a Polarized Light Microscope 1. Light Source – usually a halogen bulb that gives bright white light; it must be stable so the color don’t change by heating or voltage drift. 2. Condenser – … Read more
