From DNA Replication at ThinkQuest. In general, DNA is replicated by uncoiling of the helix, strand separation by breaking of the hydrogen bonds between the complementary strands, and synthesis of two new strands by complementary base pairing. Replication begins at a specific site in the DNA called the origin of replication.
For Meniereâs disease, destructive procedures are associated with better control of vertigo than shunt surgery, showing good control in over 90% of patients followed for five or more years. The vestibular nerve may be sectioned via the middle fossa, retrolabyrinthine, and retrosigmoid approaches, with similar efficacy.
Benign Paroxysmal Positional Vertigo (BPPV) is the most common of vestibular disorders and the most easily treated. In most patients, it can be cured with a simple physical therapy maneuver. BPPV can affect people of all ages, although it is most common in folks over the age of 60.
