It is quite different from the mRNA that takes part in protein synthesis. At 5′ end of mRNA, a cap of 7-methylguanosine (m 7 G or 7 Me G) is added. At 3′-end a tail consisting of 80-200 adenine nucleotides called Poly (A) tail is added. ADVERTISEMENTS:

WebJan 1, 2014 · A unique characteristic of eukaryotic genes are introns, or intervening sequences that do not encode for protein. These intronic sequences are excised from the transcribed mRNA and the sequences that encode for proteins, or exons, are ligated together during a process called pre-mRNA splicing. WebAug 17, 2024 · RNA splicing is the removal of introns and joining of exons in eukaryotic mRNA. It also occurs in tRNA and rRNA. Splicing is accomplished with the help of spliceosomes, which remove introns...
WebJan 30, 2024 · The eukaryotic pre-mRNA undergoes extensive processing before it is ready to be translated. Eukaryotic protein-coding sequences are not continuous, as they are in prokaryotes. The coding sequences (exons) are interrupted by noncoding introns, which must be removed to make a translatable mRNA. WebSep 5, 2024 · Processing: hnRNA needs processing (splicing) to produce the mRNA carrying the proper coding sequences.
