Module 9 Prokaryotes and Viruses
Across
- 3. A chemical secreted by a living organism that kills or reduces the reproduction rate of other organisms.
- 6. The science dealing with the description, identification, naming, and classifying of organisms.
- 7. a virus enters a cell, embeds its DNA into the DNA of the host cell, and is replicated along with the host cell DNA.
- 11. a temporary union of two organisms for the purpose of DNA transfer.
- 12. a thick internal wall produced by the bacterium that encloses the DNA and other essential parts.
- 13. Nomenclature naming an organism with its genus and species name
Down
- 1. feeds on dead matter
- 2. a noncellular infectious agent that has it has genetic material (RNA or DNA) inside a protective protein coat; it must infect a living cell to reproduce.
- 4. The process in which infection by a virus results in DNA being transferred from one bacterium to another.
- 5. an organism that causes disease
- 8. A virus enters a cell, hijacks the host cell's DNA replication system, makes copies of itself, and causes the cell to burst, releasing more virus.
- 9. a weakened or inactive version of a pathogen
- 10. The transfer of a DNA segment from a nonfunctional donor cell to that of a functional recipient cell.
