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 large bag of popcorn (about 22 cups in volume) at a movie theatre can have in it your daily allowance of sodium, and calories and fat equal to eating two Big Macs from McDonald's -- and that's before you add butter and salt to it (concession stands will add salt at the start of the popping process.).sking for butter topping can push those numbers up a bit: 1,261 calories, 79 grams of fat and 1,300 milligrams of sodium. A small bag of popcorn (about 11 cups in volume) can have absorbed six to eight teaspoons of oil during the cooking process.
