Once the DNA has been pried apart, RNA primers enter, one binds to each strand of DNA, and then DNA replication proceeds in a 5' to 3' direction. It is important to realize that there are two 5' to 3' replications happening simultaneously. These two replications are each called a replication fork.
Overview. &COPY; Reed Group Radial styloid tenosynovitis occurs when the tendons that move the thumb up or outward (away from the index finger) become painful and swollen (tenosynovitis). Symptoms are most commonly reported with repetitive gripping and twisting motions.
What are causes and risk factors of de Quervain's tenosynovitis? De Quervain's tenosynovitis can be brought on by simple strain injury to the extensor pollicis longus and abductor pollicis tendons (tendinitis). Often this form of tendinitis is a result of repetitive motion injury. Typical causes of de Quervain's tenosynovitis include stresses such as lifting young children into car seats, lifting heavy grocery bags by the loops, and lifting gardening pots up and into place.
