Normal cells greatly slow their rates of cell division after filling a culture dish with a layer that is one cell deep (a monolayer). If a circular group of cells is removed from the middle of the filled culture dish, the cells on the edges of the "wound" will begin to divide, fill the space, and then stop dividing again. How is the behaviour of transformed cells different from that?
The external faces of some of the proteins in the plasma membrane have carbohydrate groups attached to them.What role do such "sugar-coated" proteins play.
In a series of experiments, genes that code for mutant forms of a receptor tyrosine kinase are introduced into cells. The cells also express their own normal form of the receptor from their normal gene.
How did Thomas Hunt Morgan"s experiments with eye colour in Drosophila show the existence of sexlinked genes.
It is not normal to administer a pure drug to a patient. Almost all the drugs are administered in form of a medicine. A medicine is a mixture of one or more drugs combined or formulated with the other inactive materials known as excipients.
how The sex of a human is determined
define which glucose is transported across a cell membrane. I could also really use help with finding online references on similar topics.
Why is energy from fusion reactors, dissimilar that from fission reactors, so attractive from an environmental perspective. Consider the HIV enzyme called protease. The amino acid residues at the active site are highly hydrophobic.
The results of these experiments point to that plants can be genetically transformed for resistance to virus disease development. What is an expected outcome of a cross between a homozygous recessive woman and a man with hypophosphatemia.
what ways are the mechanisms of action similar. CA2+, IP3, and cAMP have all been described as second messengers.
Using a spectrophotometer set at 400 nm, an absorbance reading of 0.050 was obtained for a solution of p-nitrophenol at pH 6.5. The molar extinction coefficient of p-nitrophenol 21500 M-1cm-1 and the pka for p-nitrophenol is 7.
A researcher wants to develop a test that will distinguish charophytes and land plants from green algae. Which chemicals would be the best subject for such an assay.
as all action potentials are identical, the intensity of a sensation depends on.
