Abstract

The disclosure relates to nucleic acids that contain modifications at the 5′-end, 3′-end or 5′-end and 3′-ends, and compounds that can be used to make the modified nucleic acids are disclosed. The modified nucleic acids have improved expression, lower immunogenicity and improved stability compared to unmodified nucleic acids.
