Researchers are looking to genetics for help in unlock the secrets to better prevention, diagnosis and treatment of cancer.
The instructions for the human body are found in chromosomes and genes.
To identify genetic variations common among cancer survivors or their tumors, researchers examine nucleotides: small pieces of chromosomes. Each chromosome resembles a long and tightly coiled ladder of DNA that has supports made of sugar and phosphate groups and has rungs made of nitrogen-containing compounds known as nitrogenous bases.
The bases are usually ...
