Splicing. Eukaryotic genes are often interrupted by sequences that do not appear in the final RNA. The intervening sequences that are removed are called introns. The process by which introns are removed is referred to as splicing.The sequences remaining after the splicing are called exons. All of the different major types of RNA in a eukaryotic cell can have introns.plicing. Eukaryotic genes are often interrupted by sequences that do not appear in the final RNA.

Plain Air-Popped Popcorn Air-popped popcorn, on its own, doesn't contain many calories and is also low in fat and carbohydrates. A 3-cup serving of white, air-popped popcorn has 92 calories, 1 gram of fat and 1 milligram of sodium, according to the U.S. Department of Agriculture. The snack also has 2.9 grams of protein, 18.7 grams of carbs and 3.6 grams of dietary fiber.
A cup of plain pop only contains around 31 calories (compared to a cup of regular potato chips which holds around 139 caloriesâ¦not exactly great). Popcorn also contains fiber and is the only snack thatâs 100% whole grain. And whole grains are really good for you because they contain those antioxidants. In popcornâs case, the antioxidants are found in the hull (the seedy part that gets stuck in your teeth) and are called polyphenols. Like all antioxidants, polyphenols help protect against cancers, heart diseases, and other illnesses that are caused by free radicals (cells that attack other healthy ones).
