WebThe duplex can either inhibit protein translation by blocking the ribosome binding site, or inhibit mRNA splicing by blocking a splice site ( Fig. 5.5A ). When antisense sequences are made in the laboratory, they are usually synthesized as DNA because this is more stable than RNA (see Chapter 4 ). WebHow does antisense RNA inhibit translation?

WebA protein synthesis inhibitor is a compound that stops or slows the growth or proliferation of cells by disrupting the processes that lead directly to the generation of new proteins. [1] A ribosome is a biological machine that utilizes protein dynamics on nanoscales to translate RNA into proteins WebThe PKR kinase activity suppresses translation by phosphorylation of initiation factors and synthesis of oligo-2′–5′ poly activates the endoribonuclease RNase L, which degrades RNA. However, neither this suppression of translation nor degradation of mRNA has been shown to be gene-specific in action. lost canyon cave golf cart tour
