Steps of transformation experiment? |
|
Definition
Make POB and Glucose control plates and put ADP 6 and 1 into both. Put 1.5 mL ADP-1 in centrifuge for 2 min at 10k RPM. Discard supernatant, keep pellet. Put 300 microL TENS to pellet to lyse cells. Make serial dilutions. Prepare a POB plate with ADP-6 with spread plate technique. Divide to 4 quadrants. In quadrant 1, put 1 microL ADP-1 serially diluted by 10 --> quadrant 4, serially diluted by 10^(-3). Grow for 24 to 48 hrs. |

Difference between Transformation and Conjugation? |
|
Definition
Transformation, bacterium gets DNA from environment. Conjugation, bacterium gets DNA from another bacterium. |
|
|
Term
|
Definition
Extrachromosomal genetic element that occurs in many bacterial strains. Circular DNA, replicate independently from bacterial chromosome. Not essential for bacterium but may be an advantage. |

Difference between Auxotroph and Prototroph? |
|
Definition
Auxotroph, can't make a particular organic compound needed for its growth. Prototroph, can make all compounds needed for growth. |

Term
Why more growth at 1/10 dilution than full strength? |
|
Definition
There was still leftover TENS solution in full strength, so it killed some ADP-6 bacteria. Less TENS solution in 1/10 dilution, so didn't kill bacteria. |

Definition
Gene in cell's plasmid that can make pilus and thus perform conjugation |
|
|
Term
|
Definition
Gene to form pilus is missing in bacteria's plasmid, thus cannot perform conjugation. |
