Many mutations have no effect at all. These are called silent mutations. But the mutations we hear about most often are the ones that cause disease. Some well-known inherited genetic disorders include cystic fibrosis, sickle cell anemia, Tay-Sachs disease, phenylketonuria and color-blindness, among many others. All of these disorders are caused by the mutation of a single gene. Most inherited genetic diseases are recessive, which means that a person must inherit two copies of the mutated gene to inherit a disorder.
A modem (mo dulator-dem odulator) is a device that modulates one or more carrier wave signals to encode digital information for transmission and demodulates signals to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data.
