|
||||
|---|---|---|---|---|---|
| Competent bacteria | oly bacterial species that are competent can perform transformation--have special transport proteins in their membranes
🗑
|
||||
| Conjugation | direct transfer of DNA from one bacterium to another
🗑
|
||||
| F- cells | lack the F-factor
🗑
|
||||
| F+ cells | cells carrying any F-factor--male cells--only mate with F- cells
🗑
|
||||
| F-factor | on bacterium, the donor, contains plasmid--fertility factor--codes for pilus and other genes needed for DNA copy and transfer
🗑
|
||||
| Generalized transduction | phages that can transfer any gene from donor bacterium
🗑
|
||||
| High frequency of recombination | Hfr--F-factor integrates (inserts itself) into donor bacterial chromosome
🗑
|
||||
| pilus tip | an attachment site or ligand for specific receptors on other bacteria that lack the F-factor
🗑
|
||||
| Specialized transduction | phages that pick up just one area of donor bacterial chromosome--can transduce a limited number of bacterial genes
🗑
|
||||
| Transducing particles | contains bacterial DNA (host DNA) rather than phage DNA--when infects another bacterium--no bacteriophage grows--phage's genes missing--transfer bacterial DNA from previous host to new cell--new DNA recombines to new cells chromosome
🗑
|
||||
| Transduction | phage (bacterial virus) carries gene from one bacterium to another
🗑
|
||||
| Transformation | transform the bacteria to a different genotype--able to transport DNA from the medium into their cytoplasm
🗑

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.
