Answer:
The essential cellular machinery that is lacking for all of the viruses is ribosomes.
Explanation:
- Viruses do not have ribosomes of their own, instead, they depend on their host.
- They use the ribosomes from the cells of the host on which they are dependent for the translation of viral messenger RNA into viral proteins.
- Viruses do not synthesize proteins on their own.
- Reverse transcriptase is used for the replication of the viral genome.
- RNA polymerase and DNA polymerase enzymes play an important role in the process of viral genome replication and transcription.
