Morphology Cross-sectional model of a coronavirus Coronaviruses are large pleomorphic spherical particles with bulbous surface projections.[10] The diameter of the virus particles is around 120 nm.[11] The envelope of the virus in electron micrographs appears as a distinct pair of electron dense shells.[12] The viral envelope consists of a lipid bilayer where the membrane (M), envelope (E) and spike (S) structural proteins are anchored.[13] A subset of coronaviruses (specifically the members of Betacoronavirus subgroup A) also have a shorter spike-like surface protein called hemagglutinin esterase (HE).[5] Inside the envelope, there is the nucleocapsid, which is formed from multiple copies of the nucleocapsid (N) protein, which are bound to the positive-sense single-stranded RNA genome in a continuous beads-on-a-string type conformation.[11][14] The genome size for coronaviruses ranges from approximately 27 to 34 kilobases.[7] The lipid bilayer envelope, membrane proteins, and nucleocapsid protect the virus when it is outside the host cell.[15] Replication The infection cycle of a coronavirus Infection begins when the virus enters the host organism and the spike protein attaches to its complementary host cell receptor.
