Describe how Bacteria decode its genetic information to produce proteins? Intro(10mins) Bacteria belongs to a group of organism that lacks cell nucleus and membrane bound organells. This group of organisms are termed as prokaryotes. Prokaryotes follows the central dogma of molecular biology first proposed by Francis Crick in 1958 to synthesize proteins from mRNA through a process called translation and the mRNA is being synthesized from the DNA by another process called Transcription.

Title: Purification of Green Fluorescent Protein Introduction: Transformation is used to introduce a gene coding for a foreign protein into bacteria. Hydrophobic Interaction Chromatography (HIC) is used to purify the foreign protein. Protein gel electrophoresis is used to check and analyze the pure protein. Research scientists use Green Fluorescent Protein (GFP) as a master or tag to learn about the biology of individual cells and multicultural organisms. This lab introduces a rapid method

disease that can be a big threat to the whole town. He recommends that everyone should try and fix the baths or close them down. The Mayor‚ who is Dr. Stockmann’s brother‚ doesnt believe that there is anything wrong with the baths so refuses to make a change. He believes that it will ruin the stability of the economy. Dr. Stockman decides he will try and approach the people with his findings on the bath‚ but Peter interferes and tells the people how much more money they will need to spend in order

G-protein Coupled Receptors (GPCRs) are cell surface proteins that relay extracellular signals to the nucleus. These signals can be in the form of light‚ peptides‚ lipids‚ and sugars. Once activated by a ligand at the outer cell surface‚ GPCRs activate their cognate G-proteins that reside on the inner cell membrane. The activated G-proteins then slide along the inside of the cell membrane to activate a cascade of proteins and enzymes that in turn amplify the original message received by the GPCR

THE ROLE OF PROTEIN MISFOLDING AND AGGREGATION IN BSE When a protein misfolds it changes its behavior and function. If it becomes hydrophobic after once being polar. The properties and functionality of the protein are no longer useful to the organism and disaster results. PrPSc is hydrophobic‚ it avoids water inside of the cell…it attracts and attaches other proteins to misfolds and become hydrophobic …Misfolding spreads because the PrPSc act as chaperone proteins to convert PrPc TO PrPSc and

Practical implications – Work-related health attributions should be taken into account in order to avoid impaired levels of employee work motivation. The measure introduced renders it possible to identify and help those individuals who believe that work affects their health negatively. Originality/value – The results underscore the relevance of how individuals think their health is affected by their work‚ and contributes to the understanding of how health status relates to work-related attitudes.

Title: Estimation of Ascorbic acid Aim: To determine the ascorbic acid content of canned apple and orange juice To determine the volume of canned juice necessary to provide 75mg of Vitamin C Introduction: For the estimation of ascorbic acid‚ the method used involved the titration of the ascorbic acid‚ in the presence of a redox indicator 2‚6-dichlorophenol-indophenol (DCPIP) which acts as both an oxidant so as to oxidise the ascorbic acid to dehydroascorbic acid‚ and it acts as an indicator
