PhD position in Drosophila neurobiology @ Manchester UK

By | January 8, 2022

A PhD position is available to study bundles of microtubules (MT) that run all along axons in Drosophila brain. The decay of MT bundle decay causes axon degeneration and mechanism underlying this phenomenon forms the basis of this project. More details and link to apply: How to apply: https://www.bmh.manchester.ac.uk/study/research/bbsrc-dtp/apply Application deadline: 21 January 2022 Interviews: week commencing… Read More »

By | January 6, 2022

Post doctoral positions are available in Cassandra Extavour lab at Harvard. Positions to work on two major areas of our research are available: Holobiome Area: Understanding the animal, plant and microbial contributions to the evolution of specific adaptive traits and phenotypic plasticity, using both Drosophila melanogaster and natural populations of wild Drosophila species in Hawaii.… Read More »

How to prepare Hoyer’s medium for Drosophila cuticle preparations

By | January 4, 2022

Importance of cuticle preparations in Drosophila studies: The Drosophila embryonic ventral epidermis has served as a unique tissue for the genetic analysis of patterning. There are two different types of epidermal cells in the ventral epidermis which can be easily distinguished: those that secrete short, thick hair-like structures called denticles and cells that only secrete… Read More »

How to make a 1% agarose gel for electrophoresis

By | January 4, 2022

Agarose gel electrophoresis is the most common way of separating and analyzing DNA. Agarose is a polysaccharide, generally extracted from certain red seaweed. It is a linear polymer made up of the repeating unit of agarobiose, which is a disaccharide made up of D -galactose and 3,6-anhydro- L -galactopyranose.  Preparing 1% Agarose gel:Gels are prepared… Read More »

Do Plants breath ?

By | January 1, 2022

Breathing can be described as ” Taking in Oxygen and expelling out CO2 through lungs”. This is also called as external respiration“. What is the difference between breathing and respiration? Both breathing and respiration are vital for living organisms to survive. Even though there is a significant difference between breathing and respiration but are mostly… Read More »

What is amphibolic pathway?

By | November 9, 2021

Amphibolic pathway can be described as a kind of biochemical pathway which involves both Anabolism and catabolism pathways. The term amphibolic pathway is coined by B. Davis in the year 1961. Catabolism : A biochemical pathway where large molecules are broken down into smaller molecules. It can be by means of Hydrolysis and Oxidation. Hydrolysis… Read More »

Electron transport system and Oxidative phosphorylation – Cellular respiration ( Part – V)

By | November 1, 2021

By using electron transport system and oxidative phosphorylation steps, the cell utilizes energy stored in NADH + H+ and FADH formed during glycolysis and Krebs cycle. The Electron Transport System also called the Electron Transport Chain is a metabolic pathway present in the inner mitochondrial membrane, where electrons available from oxidation of NADH and FADH2… Read More »

Krebs Cycle – Cellular Respiration (Part – IV)

By | October 27, 2021

The fate of pyruvic acid formed at the end of Glycolysis depends on the need of the cell and also on availability of oxygen. Organisms which grow in absence of oxygen – In anaerobic organisms, fermentation takes place after glycolysis. In presence of oxygen, aerobic respiration takes place where pyruvic acid from glycolysis enter Krebs’s… Read More »

Fermentation – Cellular Respiration (Part – III)

By | October 20, 2021

Introduction : Glucose happens to be important and common fuel for many organisms. The process of breaking down of glucose in multistep manner to extract energy present in its C-C bonds (chemical bonds) is called “Cellular Respiration“. Only green plants, Algae and Cyanobacteria have the ability to prepare their own food by the process of… Read More »

Glycolysis – Cellular Respiration (Part II)

By | October 17, 2021

The breakdown of glucose to pyruvic acid in a multi step manner is called as Glycolysis. It takes place in cytoplasm of the cell. It is common pathway to both Anaerobic and Aerobic respiration. The Glycolysis pathway is a very ancient pathway present in majority of organisms from every branch of the bacteria, archaea, and eukaryotes. This… Read More »
