An Antisense RNA Inhibits Translation by Competing with …

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 ). WebMar 16, 2024 · In this study, the knockdown of plasma FXII was achieved by administering an antisense oligonucleotide, a short synthetic strand of nucleotides that targets a specific mRNA sequence to modulate and limit protein translation.
