Why does DNA damage lead to autoimmunity?Autoimmunity:Autoimmunity is the situation in which a person's immune system attacks their own cells. It is responsible for a wide range of diseases that range in severity from the inconvenient such as alopecia areata to the life-threatening like lupus....
Why/how does protein phosphorylation have profound effects on protein structure and function? Why is trypsin called universal enzyme? Why can't an enzyme that hydrolyzes starch degrade cellulose? Is an enzyme a protein or is a protein an enzyme? Explain. How do we digest/cleave plasmids? Explai...
Depending on the primer sequence and length, certain primer sets are vulnerable to the effects of frequent freeze-thawing. Over time, especially when working from the same working aliquot, your primers may degrade and become useless. Inappropriate storage of primers, such as at room temperature,...
The Chelex beads will bind divalent magnesium ions (Mg++). These ions often serve as cofactors fornucleasesthat will degrade your DNA sample and may interfere with the enzyme (Taq polymerase) used in the reaction. By removing magnesium ions, the degradation of genomic DNA by nucleases is reduce...
Heat does degrade DNA. Detecting species-specific DNA means that enough of it remained intact to find. Once found, the DNA has to go through purification before PCR is even run, and then there are filtering and other processes beyond that (11). In general applications, PCR has a ...
Plastics are continually criticized for degrading too slowly. We are told that they last forever. As we know know, that’s clearly untrue. Is it fair to single out plastics? How long does it take for the other 99% of materials we use to degrade? Let’s take a look: ...
Related: Why does hair turn gray? Skin's structural supports are largely found in the dermis, the middle layer of tissue. (Image credit: Paladjai via Getty Images) Wrinkles start to appear as these structural components of the dermis start to degrade, a process broadly known as skin aging...
3.3. Where does PMS act? Estimation of cell wall damage and membrane permeability To evaluate the possibility of primary PMS attacks on the bacterial cell wall, and therefore the localization of cell damage, malondialdehyde (MDA) generation and ortho-nitrophenyl-β-D-galactoside (ONPG) hydrolysis ...
Why does Saccharomyces cerevisiae (yeast) ferment more quickly when maltose is used instead of fructose?Yeast fermentation:Yeasts are microscopic, single-celled organisms that are widely used in the food industry as a source of fermentation.They're used in the production o...
Why can't an enzyme that hydrolyzes starch degrade cellulose? Carbohydrate digestion a) Amylase b) Pepsin c) Bile salts d) Pancreatic lipase e) Gastrin Saliva does not contain amylase until babies are about two months old. How could this affect an infant s digestion?
