DNA (deoxyribonucleic acid) is the genomic material in cells that contains the genetic information used in the development and functioning of all known living organisms. DNA, along with RNA and proteins, is one of the three major macromolecules that are essential for life.
A doctor of osteopathic medicine (D.O.) is a fully trained and licensed doctor who has attended and graduated from a U.S. osteopathic medical school. A doctor of medicine (M.D.) has attended and graduated from a conventional (allopathic) medical school. The major difference between osteopathic and allopathic doctors is that some osteopathic doctors provide manual medicine therapies, such as spinal manipulation or massage therapy, as part of their treatment. After medical school, both M.D.s and D.O.s must complete residency training in their chosen specialties.
A doctor of osteopathic medicine (DO) may specialize in pediatrics or surgery. A DO may practice any field of medicine, including pediatrics. A DO may evaluate a patient's stress level and determine what effect it is having on that person's health. A doctor of osteopathic medicine may sometimes practice manipulation of the spine, which is similar to work done by chiropractors. A DO usually uses a holistic approach to treating patients. Doctors of osteopathic medicine tend to spend more time with patients.
