Separating Proteins by Size To begin characterizing a protein, it is often useful to be able to separate it from as many other proteins in the mixture as possible. One of the first techniques that can be used is to separate it according to how big it is, otherwise known as its molecular weight. When...

Do such genetic markers exist? Markers that are present in one population (at least to a certain percentage) but not in another? Many human geneticists are eager to emphasize that genetic diversity within a population is far greater than between populations. This view is also reflected in a 2001 bac...

Chemiosmosis is relates to the generation of ATP by the movement of hydrogen ions across a membrane during cellular respiration.It will diffuse from an area of high proton concentration to an area of lower proton concentration. This could be harnessed to make ATP. He likened this process to osmosis,...

Adult stem cells Also known as progenitor cells or somatic stem cells, adult stem cells are located, in small quantities, throughout the body and generate specialized cells for the area they are located. These cells do not renew themselves as well as embryonic stem cells. Still, if these cells are p...
