Interspersed within the exons are introns, regions of non-coding DNA. Introns must be removed from the initial transcript of mRNA before the final mature transcript is sent to the ribosome for translation into protein. This removal is done in a coimplex protein structure called the spliceosome.The spliceosome splices out the non-coding introns from the primary mRNA transcript, and stiches the exons back together into the mature mRNA transcript.he spliceosome is a complex of small nuclear RNA (snRNA) and small nuclear protein (snRNP) molecules, snRNAs and snRNPs.
Calorie Breakdown. A slice of fast-food cheese pizza weighing approximately 103 g contains 272 calories, 33.56 g of carbohydrate, 12.27 g of protein, 9.8 g of fat, 4.35 g of saturated fat, 1.8 g of fiber, 551 mg of sodium and 22 mg of cholesterol, notes the U.S. Department of Agriculture's National Nutrient Database.
Cheese Pizza. A thin-crust cheese pizza will have lower carbs than a pizza with a thicker crust. For example, a slice from a 14-inch thin-crust cheese pizza weighing about 2.6 ounces contains 230 calories and 23.7 grams of total carbs, including 1.9 grams of fiber, making the net carbs 21.8 grams.Opt for a regular-crust slice of about 3.7 ounces and the calories increase to 285 and the total carbs to 35.7. slice of cheese pizza on a regular crust has 10.4 grams of fat, including 4.8 grams of saturated fat, or 16 percent of the daily value for fat and 24 percent of the DV for saturated fat. Make that a pepperoni pizza slice and the fat increases to 13.2 grams of total fat and 5.7 grams of saturated fat.
