Study Notes

Key Facts about Viruses

Viruses are basic life forms composed of a protein coat called capsid.
They do not have organelles or ribosomes.
The genetic material of viruses can be either DNA or RNA.
Viruses replicate by taking control of the host cell's synthetic machinery.
Viruses contain genetic information but not the enzyme needed for replication.
Viral morphology is determined by the structure of the nucleic acid.
RNA viruses can have different types of RNA, such as (+) stranded, (-) stranded, or retroviral RNA.
(+) stranded RNA can be immediately translated by the host's ribosomes into protein.
(-) stranded RNA needs to be transcribed into a (+) strand before translation can occur.
(-) RNA viruses carry a capsid with an enzyme called RNA dependent RNA polymerase, which transcribes the (-) strand into a (+) strand.
Translation is the process of converting the RNA into protein.
The (+) RNA is translated by the host's ribosomes to synthesize proteins.
