WebbIn eukaryotic cells, mRNA (messenger RNA) undergoes several modifications before it can be translated into protein. The process is called post-transcriptional modification and involves three main steps: Capping: After the pre-mRNA is synthesized by RNA polymerase II, a modified guanine nucleotide is added to the 5' end of the mRNA molecule. WebbProcessing of core histones is done differently because typical histone mRNA lacks several features of other eukaryotic mRNAs, such as poly (A) tail and introns. Thus, such mRNAs do not undergo splicing and their 3' …
