15.8: RNA Processing in Eukaryotes - mRNA Processing
WEBOct 31, 2023 · The three most important steps of pre-mRNA processing are the addition of stabilizing and signaling factors at the 5′ and 3′ ends of the molecule, and the removal of intervening sequences that do not specify the appropriate amino acids.
5.5: RNA Processing - Biology LibreTexts
WEBAug 31, 2023 · What are the processing steps for messenger RNAs? In eukaryotic cells, pre-mRNAs undergo three main processing steps: Capping at the 5' end; Addition of a polyA tail at the 3' end. and; Splicing to remove introns; In the capping step of mRNA processing, a 7-methyl guanosine (shown at left) is added at the 5' end of the mRNA.
Eukaryotic RNA Processing – Principles of Biology
WEBEukaryotic mRNAs must undergo several processing steps before they can be transferred from the nucleus to the cytoplasm and translated into a protein. The additional steps involved in eukaryotic mRNA maturation create a molecule that is much more stable than a prokaryotic mRNA.
3.5.5: RNA Processing in Eukaryotes - Biology LibreTexts
WEBExplain how tRNAs and rRNAs are processed. After transcription, eukaryotic pre-mRNAs must undergo several processing steps before they can be translated. Eukaryotic (and prokaryotic) tRNAs and rRNAs also undergo processing before they can function as components in the protein-synthesis machinery.
