Different mRNAs within the same cell have distinct lifetimes (stabilities). In bacterial cells, individual mRNAs can survive from seconds to more than an hour. However, the lifetime averages between 1 and 3 minutes, making bacterial mRNA much less stable than eukaryotic mRNA. In mammalian cells, mRNA lifetimes range from several minutes to days. The greater the stability … Web1 day ago · Previous studies have revealed the crucial role played by m 5 C methylation modification in mRNA mobility [6].We therefore compared 562 mRNAs harboring m 5 C modification in Arabidopsis with a set of 486 mobile mRNAs identified using the field dodder/Arabidopsis grafting system [20].The overlap between the two lists consisted of …

WebA cell is treated with a drug that prevents the formation of new lysosomes. The cell continues to transcribe the genes that code for the hydrolytic enzymes that are normally found in lysosomes and continues to translate the mRNAs for those proteins on membrane-bound ribosomes. WebApr 8, 2024 · It was also shown that long viral RNAs (such as gRNA, S, 3a, E, and M) were more frequently modified than the shorter ones (6, 7a, 7b, 8, and N), suggesting that the mechanism of RNA modification may be RNA specific (Kim et al., 2024).
