Reverse transcriptases are enzymes encoded in retroviruses viral genome. The enzyme is responsible for transcription of the viral RNA to produce a dsDNA that can be inserted into the host genome.
Pacific Ocean Basin. The Pacific Ocean is bounded on the east by the North and South American continents; on the north by the Bering Strait; on the west by Asia, the Malay Archipelago, and Australia; and on the south by the Southern Ocean.
Located between the Southern Ocean, Asia, Australia and the Americas, the Pacific Ocean occupies about one-third of the Earth's surface. Containing almost twice as much as the world's second largest body of water, the Atlantic Ocean, the Pacific Ocean holds more than half of the Earth's open water supply. In fact, the Pacific Ocean's basin, or the land below sea level, is so large that it could hold all of the world's continents. Besides being the biggest, the Pacific is also the oldest of the existing ocean basins.
