WebJul 4, 2024 · There are three main types of RNA processing events: trimming one or both of the ends of the primary transcript to the mature RNA length; removing internal RNA sequences by a process called RNA splicing; and modifying RNA nucleotides either at the ends of an RNA or within the body of the RNA. WebTranslation is the process by which mRNAs are converted into protein products through the interactions of mRNA, tRNA, and rRNA. Even before an mRNA is translated, a cell must invest energy to build each of its ribosomes, a complex macromolecule composed of structural and catalytic rRNAs, and many distinct polypeptides.

WebWhich three statements correctly describe the processing that takes place before a mature mRNA exits the nucleus? 1. A cap consisting of a modified guanine nucleotide is added to the 5' end of the pre-mRNA. 2. Noncoding sequences called introns are spliced out by molecular complexes called spliceosomes. 3. WebThe 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. In rare cases, the mRNA transcript can be "edited" after it is transcribed. 5' Capping WebJun 22, 2024 · What are the three stages of translation?
