|---|---|---|---|---|---|
| DNA taken up directly from environment by competent prokaryote/eukaryote cells. | Transformation
🗑
|
||||
| Plasmid is replicated and transferred through pilus. Plasmid DNA only, no transfer of chromosome material | F+ x F- conjugation
🗑
|
||||
| Plasmid that is incorporated into chromosome is then replicated. When transferred, plasmid and chromosomal genes are moved. | Hfr (F+ in chromosome) x F- conjugation
🗑
|
||||
| Lytic phage infects bacterium, leading to cleavage of DNA and synthesis of viral proteins. Part of bacterial chromosomal DNA may become packaged in viral capsid. Phage infects another bacterium transferring these genes | Generalized transduction (Lytic phage)
🗑
|
||||
| Lysogenic phage infects bacterium; viral DNA incorporated into bacterial chromosome. When phage DNA is excised, flanking bacterial genes may be excised with it. Dna is packaged into phage viral capsid. | Specialized transduction (Lysogenic)
🗑
|
||||
| Segment of DNA that can "jump" from one location to another. Can transfer genes from plasmid to chromosome. | Transposition
🗑
|
||||
| Jumping from plasmid to chromosome and vice versa ____, DNA taken from external environment, DNA movement involving lytic phages, DNA movement involving lysogenic phage | Transposition, Transformation, Generalized transduction, specialized transduction.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
