SDS-PAGE Electrophoresis of Proteins
... enzyme activity. Thus, enzymes must remain functional and only native gel electrophoresis can be carried out. Even though sodium dodecylsulphate-PAGE (SDS-PAGE) can be calibrated with proteins of known Mr so that the molecular mass of a polypeptide can be determined, native PAGE was used since SDS ...
Phosphorylation in Yeast.
... and tyrosine residues in eukaryotic proteins. Moreover, in prokaryotic proteins phosphorylation takes place on basic amino acid residues such as histidine, arginine or lysine. Protein phosphorylation catalysed by protein kinases plays a major role in cellular ...
Determinations of the Protein Concentration of a Cell Extract Using the 'Bradford Method'
... concentration of cell extracts (Bovine Serum Albumin, BSA) using the Bradford method. Stock solution of BSA was made by diluting the protein solution to prepare concentrations ranging from 0.0mg/cm3 to 1.0mg/cm3 (Peck, 1998). 5cm3 of the Bradford dye reagent was added to 100μl of the solution and ...
DNA Experiments
... and put them on a Petri dish with R-strain (nonencapsulated nonvirulent); the R-strain transformed, proving that proteins did not carry the genetic information. When the same experiment was conducted, but with deoxyribonuclease enzyme ... cells with heavy nitrogen in a medium containing 14N and ...
The Use of the Green Fluorescent Protein and Its Application in the Study of Biochemistry
... protein, GFP , is unique due to the chemical nature of its chromophore, which is comprised of modified amino acid residues within the polypeptide (Prasher D.C. et al. 1992, p. 229). The three amino acids; Ser65, Tyr66 and ...
Scientific Review of A Journal Related To The Discovery of Arsenic-based Dna In A Particular Strain of Bacteria, Published In December 2010
... of instability and varied bond lengths make it difficult for enzymes to function and thus all other mechanisms which are enzyme ... unlike arsenate compounds; it allows any biological pathways and processes to progress uninterrupted (Fekry, Tipton, P.A. & Gates, ... http://www.sciencemag.org � PAGE ...
Penguins
... in the water. Their prey can be found not far from the surface. They catch prey in their beaks and swallow them whole and swim at the same time! Penguins for the most part breed in large colonies. Living in colonies results ...
A Closer Look at Pain
... protein-digesting enzyme called aggrecanase. Aggrecanase degrades the cartilage protein called aggrecan, which contributes to the compressibility and ...
A letter about growing tomotoes in greenhouses and pesticides
... a mineral solution pumped around the plant roots. Removing the soil removes soil organisms which can cause disease. Monitoring and adjusting the concentrations of minerals in the solution enable you to control growth. It allows your tomatoes to be grown in regions ...
Give an account on the molecular structure of carbohydrates
... molecular structure of carbohydrates Carbohydrates contain the elements of carbon, hydrogen and oxygen. Examples of carbohydrates include sugars and ... cell walls and gives the cell wall strength and ...
