Cancer research. Conceptual computer artwork of a cancer cell (orange) overlaid with the bands of a DNA (deoxyribonucleic acid) autoradiogram. This could represent research into the inherited risks of cancer, which is often due to damage to DNA (genetic material), causing an uncontrolled spread of cells that is called cancer. The cell has been imaged using a scanning electron micrograph. The bands of the autoradiogram represent the sequence of the nucleotide bases that form the genetic code found in DNA.
