Cholera develops when the bacterial toxin prevents G-protein inactivation , which leads to the continuous production of cAMP.
The tertiary structure of a protein refers to the overall three-dimensional arrangement of its polypeptide chain in space. It is generally stabilized by outside polar hydrophilic hydrogen and ionic bond interactions, and internal hydrophobic interactions between nonpolar amino acid side chains
Answer:
The main purpose of Negative staining is to study the morphological shape, size and arrangement of the bacteria cells that is difficult to stain. eg: Spirilla. It can also be used to stain cells that are too delicate to be heat-fixed. It is also used to prepare biological samples for electron microscopy.
Secondly, what are the limitations of simple staining? Disadvantages. It does not give much information rather than the morphological characteristics of bacteria. Through simple staining, we cannot classify a particular type of organism.
Regarding this, what is an example of a negative stain?
In a negative staining technique, an acidic, anionic dye is mixed with a cell sample. The dye changes the color of the background, not the cells, causing the cells to stand out. India ink is the classic example of a negative stain.
Conventional genetic analyses of rRNA sequence is not possible for prions because they don't contain nucleic acid.Prions do not contain genetic material such as - DNA and RNA.
The unique traits and genetic material information are encoded with the conformation structure and modification of protein.Prions which are responsible for transmissible sponginess encephalitis is mammals which all known prion disease affect the neural tissues.
There are 253 amino acids exist in multiple conformations and isoform which is found in healthy organisms, most extensively studied proteins. Prions are not destroy easily and remains intact in the presence of radiation , disinfectant and extreme heat.
