Thinking about the functions of testosterone, the functions of epinephrine, and the nature of enzymes, which hormone pathway is likely to have a swifter effect?
To make up a solution of phosphate buffered saline (PBS), you need 15 mM Na2HPO4 (anhydrous) (FW: 141.96 g/mol), 0.25 M NaCl (FW: 58.44 g/mol), and 2 mM KH2PO4 (FW: 136.09 g/mol).
Sulfhydryl groups have the ability to react with the alkylating reagent N-ethylmaleimide (NEM) in chemical modification experiments. When NEM is added to a purified solution of creatine kinase, Cys
You need to prepare a stock solution of medium for your culture cells, which usually includes liquid salt solution and bovine serum. Your liquid salt solution is supplied in a 50X concentration, and
I am familiar with the Jmol, Rasmol and PyMoL softwares, and was recently introduced to BioBlender. However, I am completely unaware if any of these programs (or others) are capable of loading a .pd
Surveys show that 0.6 percent of the US population has an allergic reaction to peanuts. This prevalent allergy has even prompted some to ban peanuts from schools altogether.
I understand that mass spec is widely used to study PTMs like glycosylation of proteins, but how can mass spec determine correct PTM structure of say glycosylation if two glycan structures have the
Parthenogenesis is the development of EGG into new individual so, how can egg be developed into male because egg won't have that "Y" chromosome required for male offspring
You have 12 mL of cells you need to treat with Hydrogen Peroxide (H2O2), such that the final concentration of H2O2 is 50 uM.
The doctor suspected the patient was using anabolic steroids so he ordered an additional test. The doctor discovered circulating levels of stanozolol, which is a banned anabolic steroid, in the pati

I understand that different types of cell will have a different number of Organelles in them, (e.g. there might be some very simple cells with 10 but there might be some with many more than that) bu
However, sudden changes are possible in the level available of a certain protein. An example could be sudden depletion of SNAREs (required for vesicle fusion in neurotransmitter exocytosis) caused b
Many willows (Salix spp.) grow in northern states but do not grow in southern states, for example Salix viminalis.
I've heard that THC can cause permanent damage to brain cells. I've also heard this reffered to anti drug propaganda. Another theory i've read is that temporary effects reduce intelligence but long
There are several families of antibodies found in mammals. They may have two or more antibody domains which contain heavy and light chains. The variable regions of the light and heavy chains genes i
I had a colleague ask me recently whether mRNAs could be sequenced directly. I found this Nature paper published by Helicos in 2009, in which they describe their developments in the area.
But since now the entire genome can be sequenced pretty cheaply both in time and money, what is the unique value of recombination-based genetic mapping?
When a biologist is talking about a genetically engineered mouse strain which is a "tool strain".
Almost every journal article I read in the cell biology field almost always reports things like P values and stats tests to report statistical significance, but should effect sizes be more important
In a single neuron, the amplitude of an action potential does not depend on the strength of the stimulus. However, in your experiment, as you increased the stimulus strength the amplitude of the res
As I know three nucleotide pairs (triplus) code one gene. But I have found next information in the "Molecular biology of the cell" by Bruce Alberts: Mycoplasma genitalium: it has only about 480 gen
'polyploidy is when the number of chromosomes in an organism's cell doubles. This means that the organism has more chromosomes than other individuals of the same species, meaning it cannot mate with
Blender companies state that a blender for smoothies should have speeds of at least 30000 rpm. They argue that only at 30000 rpm are cells of fruits and vegetables sheared enough to maximize nutriti
Is trisomy mostly due to complications with fertilization? If so, does in vitro fertilization reduce the probability of trisomy for the fetuses of older mothers?
