<span>The metabolic activity of a specific region of the living rat brain can be revealed by measurement of Fos protein concentration.
c-Fos is a proto-oncogene that is the homolog of the retroviral oncogene v-fos. It was first discovered in rat fibroblasts as the transforming gene of the FBJ MSV.</span>
DNA and RNA both contain a cyclic nitrogenous base, a posphate group and a five-carbon sugar. These are the base units of nucleotides which make up nucleic acids. DNA contains the nitrogenous bases; adenine, thymine, cytosine and guanine wheresas RNA contains the bases; adenine, thymine, cytosine and urasil. DNA codes for the nucleotides in an RNA molecule, whereas DNA codes for the amino acid sequence in a protein
<span>Several types of relationship exist between living organisms in an ecosystem. When two different species of animals depend on the same king of food for survival, this type of relationship is called COMPETITION. In competition relationships, the fittest usually survival.</span><span />
