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.
A total of four to six grams of saturated fat in two slices of this kind of pizza is actually not much considering the recommended limits for saturated fat are 18 to 22 grams a day, or 12 to 17 grams for those with high blood cholesterol.
