Module 9

7. Chemical secreted by a living organism that kills or reduces the reproduction rate of other organisms.
10. A virus enters a cell, embeds its DNA into the DNA of the host cell and is replicated along with the host cell's DNA.
11. A Organism that causes disease
13. The process in which infection by a virus results in DNA being transferred from one bacterium to another.

1. Naming an organism with its genus and species name.
2. A virus enters a cell, hijacks the host cell replication system, makes copies of itself causing the cell to burst to releasing more viruses
3. a temporary union of two organisms for the purpose of DNA transfer
4. A non-cellular infectious agent that has two characteristics: (1) It has genetic material (DNA or RNA) inside a protective protein coat. (2) It cannot reproduce on its own; it must infect a living cell.
5. A thick internal wall (made of several hard layers), produced by the bacterium, that encloses its DNA and other essential parts.
6. The transfer of a DNA segment from a nonfunctional donor cell to that of a functional recipient cell.
8. a organism that feeds on dead matter
9. A weakened or inactive version of a pathogen that stimulates the body's production of antibodies that aid in destroying the pathogen.
12. The science dealing with the description, identification, naming, and classifying of organisms.
