DBT-JRF notes [Crabtree and Warburg effect]

 Crabtree effect:

The name is given by an English Biochemist Herbert Grace Crabtree. 

This effect is referred to as the production of ethanol in aerobic conditions rather than biomass by yeast cells at high external glucose concentrations through the TCA cycle. 



This is basically the decrease in the rate of electron transport due to the mass action of the elevated phosphorylation ratio. 

Warburg effect:

This effect is referred to as an increase in the rate of glucose uptake and the production of lactate in aerobic conditions. The discoverer of this effect, 

Warburg hypothesized that this effect is mainly due to the dysfunctional mitochondria, observed in the tumor cells, predominantly found in the cancer developmental cells. 



The Crabtree-Warburg effect interprets that the avoidance of a decrease in ATP is observed in those conditions where higher glucose uptake is found than the downstream processing capability of the second phase of the glycolysis.

INTRODUCTION TO RECOMBINANT DNA TECHNOLOGY(RDT) WITH ITS STEP AND APPLICATION

  INTRODUCTION TO RECOMBINANT DNA TECHNOLOGY(RDT) - Devlina Sarkar v What is Recombinant DNA technology ? RDT is a series of procedures that is used to join together (recombine) DNA segments from different organisms and inserting it into a host organism to produce new genetic combinations. v What is called Recombinant DNA ? Recombinant DNA (rDNA) is   m olecules  of  DNA  from two different species that are inserted into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture, and industry. Recombinant DNA in a living organism was first achieved in 1973 by  Herbert Boyer , of the University of California at San Francisco, and  Stanley Cohen , at Stanford University , who used   E. coli  restriction enzymes to insert foreign DNA into plasmids. v What is the basic use of RDT? Using RDT we can get a huge no of copies/clones of a particular gene or DNA(cloning) by usi...

COVID 19 - A brief details about COVID-19 , HISTORY, STRUCTURE, MODE OF TRANSMISSION, MODE OF ACTION and SYMPTOMS

 COVID-19 - Eishika Das,  -Soumyaprabha Ganguly HISTORY:  Coronavirus disease 2019  ( COVID-19 ) is an  infectious disease  caused by  severe acute respiratory syndrome coronavirus 2  (SARS-CoV-2) The disease was first identified in 2019 in  Wuhan , the capital of  Hubei , China, and has since spread globally, resulting in the  2019–20 coronavirus pandemic . According to the World Health Organization (WHO), viral diseases continue to emerge and represent a serious issue to public health. In the last twenty years, several viral epidemics such as the severe acute respiratory syndrome coronavirus (SARS-CoV) in 2002 to 2003 beginning in China and involving two dozen countries with approximately 8000 cases and 800 deaths , and H1N1 influenza in 2009, have been recorded. Most recently, the Middle East respiratory syndrome coronavirus (MERS-CoV) was first identified in Saudi Arabia in 2012 approximately 2,500 cases and 800...
