uncoating

uncoating

(ŭn-kōt′ĭng)
The release of viral nucleic acids from the capsid that covers them. Uncoating of viruses can be complete or incomplete and can occur before a virus enters the cell or after it penetrates a cell membrane.

uncoating

the removal of protein coat or envelope from a virus, one of the first steps in replication which releases the viral genome and enables viral genes to become available for transcription.
