Homework Answers
All the statements above are true for Ti plasmid.
•In certain circumstances Ti plasmid behave as conjugative plasmid in promoting the conjugation of bacteria and transfer of plasmids
•In plant genetic engineering, Ti plasmid used for transfer of genes between bacteria and plant cells.

The substrate used for blue-white screen is called: B-galactosidase. X-gal. Ampicillin. Blue colony. The Ti plasmid is: A conjugation plasmid. Used for transfer of genes between bacteria and plant cells. Encodes genes that force plant cells to produce products that are beneficial to the bacteria. All of the above. During Southern blotting, describe the difference between migration and separation of DNA fragments.

13. Which of the following statements about conjugation is false? A) Conjugation is sexual reproduction for bacteria B) In conjugation a bacterium carries a fertility plasmid. C) In conjugation a bacterium forms a small hollow tube called a pilus. D) In conjugation a bacterium attaches to a neighboring bacterial cell that lacks a fertility plasmid. E) Conjugation can be a problem because fertility plasmids often carry genes that endow cells with drug resistance or the ability to produce toxins.

D. Natural selection acts on the classes of antibiotics and the individual antibiotics evolve. T 8. How do bacteria that have never been treated by antibiotics acquire genes for antibiotic resistance? (1 pt) These bacteria are naturally resistant to all antibiotics. II. During conjugation, two bacterial cells form a bridge between them and exchange genetic information. This can transfer resistant genes from one cell to another (also known as horizontal gene transfer, plasmid exchange). Bacteria chose to join resistant populations...

Illustrate a conjugation event with an F’ cell that is lacIS lacP+lacO+lacZ- lacY-on the bacterial chromosome and lacI- lacP+ lacOC lacZ+ lacY+ on an F plasmid with an F-cell that is lacI+ lacP+ lacO+ lacZ+ lacY-. Draw both cells before the conjugation event, as well as the recipient cell after conjugation occurs. Underneath all three cells, note whether the production of permease and beta-galactosidase would be high, basal, or none, and describe HOW the proteins and DNA sequences interact to...

Bacillus thuriniensis is an example of a bacteria used in agricultural applications. Why is this microbe used in these applications? It contains a Ti-plasmid that gives octopines to the plant. It liberates soil phosphorus to help the plant obtain phosphorus. It produces a compound called Bt-toxin that kills insect pests. It produces a potent antibiotic that fights off pathogenic microorganisms.

Transgenic plants can be generated using T-DNA plasmid carrying a gene of interest. To get the DNA into the plant cells, the researchers a. use a syringe needle to inject the DNA into pollen before fertilization b. use a syringe needle to inject the DNA into groups of cells in the plant’s root tissue c. co-cultivate bacteria that produce T-DNA along with plant cells, resulting in DNA transfer d. add a mild detergent to cultures of plant cells to open...
