This scientific animation describes one of the strategies for targeting coronaviruses (e.g. the novel coronavirus, SARS-CoV-2) by "tricking" the virus enzyme RdRP into incorporating nucleotide/nucleoside analogues into the emerging RNA-chain instead of the normal nucleotides. This group of compounds contain for instance Remdesivir and Galidesivir. This animation was made by Ann-Louise Bergström / Moving Science (www.movingscience.dk) and the music was made by Frédéric Eghiaian.
