mRNA splicing is a fundamental part of the ... a process facilitated by splicing enzymes. In the new study, the Caltech researchers examined a particular type of nuclear body, called the nuclear ...

RNA repair enzymes capable of sealing 2’,3’-cyclic-PO 4 /5 ... and stress response pathways involving the repair of tRNA breaks (during tRNA splicing) and mRNA breaks (during the unfolded protein ...

The introns need to be cut out of the pre-mRNA in the cell nucleus and the exons reconnected at the interfaces. This process is known as splicing. Ultimately, the spliced messenger RNA consists of ...

From splicing and polyadenylation ... Over the past five years, most of the enzymes involved in mRNA decay have been identified and we are beginning to unravel the complex regulation that ...

During splicing, introns are excised ... It protects the mRNA from degradation by cellular enzymes and aids in the initiation of translation. The poly-A tail, a chain of adenine nucleotides ...

“You’re using them to mask critical regions on an mRNA that’s being processed to allow the splicing machinery ... are quickly degraded by various enzymes. To be effective, any RNA-based ...

The resulting primary transcript, known as pre-mRNA in eukaryotes ... Other ribozymes include self-splicing introns and the RNA component of the enzyme telomerase. Non-coding RNA molecules, such as ...

Research into splicing mechanisms and patterns is essential for decerning fundamental biological principles, as well as clarifying the molecular basis of many diseases and developing new therapies. 2 ...

Despite these structural features, mRNA molecules are relatively unstable compared to DNA. They have a shorter lifespan and are prone to degradation by cellular enzymes called ribonucleases (RNases).
