WebRNA molecules perform a variety of roles in the cell but are mainly involved in the process of protein synthesis (translation) and its regulation. RNA Structure RNA is typically single stranded and is made of ribonucleotides that are linked by phosphodiester bonds. WebUsing a class of engineered molecules called short interfering RNA (siRNA, for short), scientists have shown that the viral mRNAs synthesized by the Ebola virus inside infected cells can be captured and destroyed before they are able to deliver their genetic messages to the ribosomes of a host cell. No Ebola mRNA, no Ebola proteins.
