RNA Processing topics include: RNA processing, coding and non coding RNA, ribosomal processing, eukaryotic messenger, introns removal from rna by splicing,alternative splicing forms and mRNA degradation. RNA processing is a series of events that transforms a primary transcript from a gene into its mature form.  In eukaryotes, RNA processing occurs in three steps: 5' capping: The first processing event that occurs before translation. This process involves adding a 7-methylguanosine cap to the 5' end of the primary transcript. Polyadenylation: This process involves adding a string of... Show more
