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.

Sodium in Biscuits. The favorite choice for the term Biscuits is 1 2-1/2 Plain or Buttermilk Biscuit which has about 350 mg of sodium. The amount of salt (sodium) for a variety of types and serving sizes of Biscuits is shown below.
The calorie in a biscuit depends on the size. A 4-inch diameter biscuit contains 357 calories, a 2 Â½-inch diameter contains 212 calories and a 1 Â½ -inch diameter contains 49 calories.
