Terminology: Envelope


A virus is made up of micro-particles of nucleic acid (DNA or RNA) that carries genetic information and micro-particles, consisting of protein (capsid), that surround these.

There are some viruses that are further covered by a membrane containing protein, fat, or lipid, and this outer shell is called an envelope.

Additionally, there are viruses having glycoprotein spikes on top of this membrane of which the ‘H spike’ and the ‘N spike’ are well known.
