In cells, protein-RNA binding is involved in a variety of physiological regulation and developmental processes. Direct protein-RNA interactions occur during mRN
By purification on DEAE cellulose columns, small amounts of DNA, large molecular RNA, proteins, polysaccharides and other impurities were removed, and finally a
The splicing of eukaryotic pre-mRNA is a two-step process, in which an intron is cut from the precursor and two exons are joined together to form the mature mRN
Changes in the environment of the cell, the state of the replication cycle, and the state of differentiation can cause changes in the half-life of some mRNAs. T
Cytosolic extracts can be used for splicing of precursor mRNAs. The S100 extract, although it includes many splicing factors, does not have splicing activity be
Precursor mRNA ( pre-mRNA ) splicing factors The SR (serine/argininc rich) family of proteins is an important player in the assembly of splices onto precursor m
RNA can also be synthesized in vitro by RNA polymerases (e.g., T3, T7, or SP6 ) using linear DNA as a template. This experiment is based on the "RNA Laboratory
