43. b. use the host cell to copy themselves and make viral proteins.
Viruses use host enzymes for replication and also for protein synthesis as they lack ribosomes.
44. c. budding …..cell membrane
Viral envelopes are formed by budding from the hose cell and are modified cell membrane.
Viruses bud out from host cell taking part of their cell membrane with it which forms the envelope.
45. a. + ssRNA
+ ssRNA is equivalent to mRNA whereas - ssRNA is complementary to mRNA.
46. B. - ssRNA
- ssRNA use this enzyme to make + ssRNA which is equivalent to mRNA so that they can synthesize proteins.
