This type of mutation is called a nonsense mutation. It's a point mutation that turns one codon into a stop codon. Nonsense mutations always result in the early termination of a polypeptide. In other words, the chain stops short, and the protein is never completed. Our pony doesn't get any feathers, and he'll never be able to fly.
Port Arthur is located approximately 97 kilometres (60 mi) south east of the state capital, Hobart, on the Tasman Peninsula. The scenic drive from Hobart, via the Tasman Highway to Sorell and the Arthur Highway to Port Arthur, takes around 90 minutes and covers approximately 96 kilometres (60 mi).
Port Arthur was incorporated as a city in 1898 and soon developed into a seaport. It eventually became the center of a large oil refinery network. The Rainbow Bridge across the Neches River connects Port Arthur to Bridge City.
