Figure 1: Pre-mRNA splicing. Splicing of a pre-mRNA molecule occurs in several steps that are catalyzed by small nuclear ribonucleoproteins (snRNPs). After the U1 snRNP binds to the 5â² splice site, the 5â² end of the intron base pairs with the downstream branch sequence, forming a lariat.igure 1: Pre-mRNA splicing.

One Egg Biscuit sandwich from McDonaldâs has 300 total calories. This value represents 15 percent of the USDA recommended daily amount of calories for people following a 2,000-calorie diet. One serving of a McDonaldâs Egg Biscuit has 110 fat calories that contribute to the total calorie value. Each sandwich has 12 g total fat and 260 mg cholesterol. One sandwich contains 19 percent of the USDA recommended daily amount of fat for a 2,000-calorie diet. Saturated fat contributes 5 g to the total fat content.
