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 of the key differences in the biscuit mixing method and the muffin mixing method is that for the biscuit method you use solid fat, almost always cold solid fat, and the muffin method you will use a liquid fat. For these biscuits we are using very cold, real, unsalted butter cut into small pieces.
