WebAug 10, 2024 · Explanation: Introns are the sequences that do not code for any proteins. The newly formed RNA of eukaryotes have both introns and exons. Introns are removed from … WebThe maturation of mRNA in eukaryotes involves the removal of these intervening sequences or introns by a process called splicing. The process of splicing is carried out by complexes called small nuclear RNA particles (snRNPs) also called ‘snurps’. These particles are formed by small nuclear RNA (snRNA) along with multiple proteins.

WebIn prokaryotes, the primary mRNA transcript is functional as soon as it is synthesized. This is seen when ribosomes bind to the free 5′ end, even before the remainder of the molecule is transcribed. (Remember that synthesis is 5′ to 3′, so the 5′ end of mRNA is synthesized first.) WebEukaryotic mRNAs last for several hours, whereas the typical E. coli mRNA lasts no more than five seconds. Pre-mRNAs are first coated in RNA-stabilizing proteins; these protect the pre-mRNA from degradation while it is processed and exported out of the nucleus.
