WebDec 1, 2024 · capsid: [noun] the protein shell of a virus particle surrounding its nucleic acid. WebCapsid assembly is complex, and occurs with the help of scaffold proteins. Nascent capsids are filled with viral DNA (through the portal complex) in a process that requires energy. DNA is packaged in a “headful” mechanism whereby concatemers are cleaved at conserved sequences that define the genome ends. The DNA is tightly packed, producing ...
