The structural and biochemical information it provides is helpful in the diagnosis of abnormalities without the possibly harmful effects of X rays or gamma rays. It is invaluable in detecting and delineating tumours and in providing images of the brain, the heart, and other soft-tissue organs. MRI may produce anxiety because the patient must often lie quietly inside a narrow tube. Another disadvantage is that it requires a longer scanning time than other computer-assisted forms of scanning, which makes it more sensitive to motion and of less value in scanning the chest or abdomen. However, MRI images provide better contrast between normal and diseased tissue than those produced by other computer-assisted imagery. Link to file: http://www.filefactory.com/file/b00b58d/n/MRI.rar
molecular biology Field of science concerned with the chemical structures and processes of biological phenomena at the molecular level.
Having developed out of the related fields of biochemistry, genetics, and biophysics, the discipline is particularly concerned with the study of proteins, nucleic acids, and enzymes. In the early 1950s, growing knowledge of the structure of proteins enabled the structure of DNA to be described. The discovery in the 1970s of certain types of enzymes that can cut and recombine segments of DNA (see recombination) in the chromosomes of certain bacteria made recombinant-DNA technology possible. Molecular biologists use that technology to isolate and modify specific genes (see genetic engineering). link: http://www.filefactory.com/file/b00b64h/n/Bruce_Alberts_-_Molecular_Biology_of_The_Cell.pdf
