13890310484viral transductioncontributes to bacterial genetic variation0
13890313051horizontal gene transferThe transfer of genes from one genome to another through mechanisms such as transposable elements, plasmid exchange, viral activity, and perhaps fusions of different organisms.1
13890315206lytic cyclea viral reproductive cycle in which copies of a virus are made within a host cell, which then bursts open, releasing new viruses2
13890328373lysogenic cycleA phage replication cycle in which the viral genome becomes incorporated into the bacterial host chromosome as a prophage and does not kill the host.3
13890344834Which cycle allows for genetic variation in viruses?Lysogenic cycle4
13890357422prophageA phage genome that has been inserted into a specific site on the bacterial chromosome.5
13890363036BacteriophageA virus that infects bacteria6
13890372090retrovirusAn RNA virus that reproduces by transcribing its RNA into DNA and then inserting the DNA into a cellular chromosome; an important class of cancer-causing viruses.7
13890375889reverse transcriptaseAn enzyme encoded by some certain viruses (retroviruses) that uses RNA as a template for DNA synthesis.8
13890375890vertical gene transfertransfer of genes from an organism to its offspring9
13890402133sex piliappendages that pull two cells together prior to DNA transfer from one cell to the other10
13890406880Viral recombinationMultiple strains of virus infect a host simultaneously and swap genes.11

Need Notes?

While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss. Drop us a note and let us know which textbooks you need. Be sure to include which edition of the textbook you are using! If we see enough demand, we'll do whatever we can to get those notes up on the site for you!
