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.
One large, 77-gram buttermilk biscuit contains 281 calories. Perhaps more importantly from a health standpoint, it has almost 13 g of fat. In contrast, a slice of multigrain bread also weighing 77 g contains 204 calories and 3.26 g of fat.
