biochemistry to disease etiology‚ diagnosis and treatment. Biochemistry II starts with a review of two areas crucial to normal‚ healthy cellular functioning. The structure and function of biological membranes‚ in particular the variety of cell signal transduction paradigms and the biochemistry of hormones. The structure‚ function and replication of the cell’s genetic material. This information is reviewed in a series of lectures on DNA‚ the genetic code‚ protein synthesis and aspects of molecular biology

through the hydrophobic core of the lipid bilayer‚ and peripheral proteins‚ which are appendages that are attached to the surface of the membrane. These proteins have many functions for the membrane including transport‚ enzymatic activity‚ signal transduction‚ cell-to-cell recognition‚ intercellular joining‚ and attachment to the cytoskeleton and the extra cellular matrix. The fluidity of the membrane‚ according to this model‚ is important because it allows for the processes of endocytosis and exocytosis

spectrophotometer.Serial dilution was used for this experiment and it was very important.Because of the serial dilution‚we measured the number of yeast cells. The graph of growth curve was drawn and bacterial life cycle was understood with the graph.The purpose of the experiment was to calculate and draw bacterial growth curve. INTRODUCTION In this experiment‚we learnt cell growth.Cell growth means increase in the quantity of cellular constituents.Cells in culture double its number because they produce

Advanced Food hygiene Assigment question 6 Non Bacterial Food Posioning Food poisoning can be caused by the consumption of food contaminated by substances other than bacteria. This can occur by contamination of the food by chemicals‚ the ingestion of poisonous plants and by eating fish or shellfish that have been feeding on poisonous plankton or living in contaminated waters. Several foods contain naturally occurring poisons. This is more common in plants; there are hardly any animals that are

Liquid or fluid appearance is visible. Bacteria and background don’t have a much of difference in color. Although‚ bacteria are defined and visible noted. Most of the time they are single round cells. In direct stain with crystal violet‚ again background is colorless and glossy. Bacteria is blue and some

What kind of molecules can and cannot pass easily across a lipid bilayer? Structure of a lipid bilayer A lipid bilayer is a membrane mainly composed of lipid molecules‚ usually a phospholipids (See Figure 1). Phospholipids are formed from 3 components :- (1) 2 fatty acids tails – these are hydrophobic; (2) a negatively-charged hydrophilic phosphate group; and (3) a glycerol backbone. The bilayer structure is favourable energetically because the hydrophobic fatty acid tails cluster

CNTF Signaling Pathway Ciliary neurotrophic factor receptor (CNTF) also known as Akt contains three isoforms and regulates metabolism etc. Activation occurs down stream of P1-3K pathway. GSK is important and dysregulation of PK3 leads to Cancer‚ Diabetes and Schizophrenia. 2. Notch Signaling Pathway The Notch signaling pathway is a fundamental signaling system used by neighboring cells to communicate with each other in

Formal lab report: Abstarct: The Purpose of this experiment was to perform Agrobacterium-mediated transformation in Wild type Arabidopsis thaliana Columbia by using somatic plant transformation method. The whole process lasted for over a period of 11 weeks and we were successful in getting transformed plants. Agrobacterium tumefaciens strain containing pMP90 (Ti-helper) plasmid and pCAMBIA1391 (T-DNA) plasmid was used for this plant transformation. pCAMBIA1391 plasmid was constructed by cloning Brassica
