Defective virus

Defective virus

(Science: virology) a virus genetically deficient in replication, but that may nevertheless be replicated when it co-infects a host cell in the presence of a wild type helper virus.

most acute transforming retroviruses are defective, since their acquisition of oncogenes seems to be accompanied by deletion of essential viral genetic information.
