What is an oncogene and why are they important?
Onco= cancer, gene WIKIPEDIA FOR BOTH: An oncogene is a modified gene, or a set of nucleotides that codes for a protein, that increases the malignancy of a tumor cell. Some oncogenes, usually involved in early stages of cancer development, increase the chance that a normal cell develops into a tumor cell, possibly resulting in cancer. Oncogenes are dominant gain of function mutations. Allosteric enzymes are enzymes that change their shape, or conformation, upon binding of a modulator. The word allosteric comes from the Greek allos,’other’ and ‘stereos’, ‘shape’. An allosteric enzyme is an oligomer whose biological activity is affected by altering the conformation(s) of its tertiary structure. Allosteric enzymes tend to have several subunits. In some cases the regulatory site(s) and the active site are on separate subunits.
