WebDNA (gene) transcription produces precursor-mRNA (pre-mRNA) that contains both introns and exons. The 5′ cap is 7-methyl guanidine. The enzyme poly (A) polymerase adds the poly (A) tail. The process of splicing involves removal of introns from pre-mRNA and joining together the exons to form mature mRNA. Web17 aug. 2024 · Pre-mRNA contains more nucleotides than are needed to code for a protein. So, with the help of spliceosomes, the introns are removed and the exons are joined together. Next, a 5' cap and a poly(A ...

Pre-mRNA has both introns and exons. As a part of the maturation process, RNA splicing removes the non-coding RNA introns leaving behind the exons, which are then spliced and joined together to form the mature mRNA. Splicing is conducted by the spliceosome. The spliceosome is a large ribonucleoprotein which cleaves the RNA at the splicing site and recombines the exons of the RNA. Similar to polyadenylation, alternative splicing can occur, resulting in several possible prot… WebRNA polymerase is the enzyme responsible for mRNA synthesis during transcription. The newly synthesised mRNA is known as pre-mRNA, and it goes through post-transcriptional modifications to become a mature mRNA molecule.
