A) They infect the multicellular brown algae. B) They integrate their viral genome into the host cell genome. C) They are found in both marine and freshwater environments. D) They only infect the free-swimming gametes of their host. E) Productive replication of the virus makes the host sterile.
Which of the following statements describes a characteristic of the late genes of the phycodnavirus PBCV-1?
A) They are only transcribed after DNA synthesis has begun. B) They are transcribed by the host cell RNA polymerase. C) They encode structural proteins. D) They were detected by hybridizing RNA to probes of each viral gene. E) All of the above are characteristics of late genes.
