Question
A.) Transformation is best described as:
Group of answer choices
The integration of foreign DNA into a genome
The uptake of naked DNA from the environment
The transfer of DNA via a bacteriophage
Transfer of a plasmid from one organism to another
B.) What is the function of the araC gene in the pGLO plasmid?
Group of answer choices
It encodes the protein that glows under ultraviolet light
It allows us to select for the cells that contain the plasmid
It prevents the transcription of the green fluorescent protein unless arabinose is added
It ensures that the plasmid will be copied and passed on to daughter cells
C.) What is the function of the bla gene in the pGLO plasmid?
Group of answer choices
It encodes the protein that glows under ultraviolet light
It allows us to select for the cells that contain the plasmid
It prevents the transcription of the green fluorescent protein unless arabinose is added
It ensures that the plasmid will be copied and passed on to daughter cells

- You first need to create a plasmid. What are the minimal components necessary to develop this plasmid? In addition to these components, please draw the plasmid. In this illustration, I am looking for the components, the direction of transcription (i.e., the direction the genes will be transcribed), and what should be transcribed last? Also, where would you specifically insert the P. falciparum gene in this plasmid, and why are you checking reading frames in your gene? Finally, please name your plasmid using the correct nomenclature too. You are excited you have this new plasmid; you want to transfect it into P. marinus and provide it as an oral vaccine to laboratory mice. However, even though your supervisor enjoys your enthusiastic attitude, they do not allow you to do this quite yet because all you have is this plasmid. Why doesn’t your supervisor allow you to use the laboratory mouse for this research regarding animal welfare guidelines? Your answer should include the 3 R’s of…arrow_forwardOne of the reasons why phage therapy has not been applied widely is that bacteria can become resistant to bacteriophages as well, through mutations in genes encoding for specific proteins. What would be a protein in the bacterial cell that, if mutated, would make that cell resistant to phage infection?arrow_forwardA plasmid contains genes for ampicillin resistance and chloramphenicol resistance and has single sites for Hind III and Eco RI. When genes are inserted into the Eco RI site, transformants are resistant only to ampicillin. In which region is the site for EcoRI located? Group of answer choices within the chloramphenicol gene between the ampicillin and chloramphenicol genes can't be determined within the ampicillin genearrow_forward
- a. What is the purpose of molecular cloning?b. What purpose do selectable markers serve in vectors?c. What is the purpose of the origin of replication in aplasmid vector?d. Why do cloning vectors have polylinkers?arrow_forwardWhat is a plasmid? What are the minimum 3 components that a recombinant plasmid used for genetic transformation should have?arrow_forwardThe modifiedplasmid is reintroduced back into Rhizobium(step 4) and the genetically transformed bacteria are then selected based on the amp and lacZgenes present within the plasmid. The plasmid may or may not integrate the BBW resistancegene. The treated bacteria may or may not take up the modified plasmid. a) Complete the table below with a yes or no in each space stating whether you would expect these bacteria to grow or not. Type of treated bacteria culture plate(no amp) Culture plate treated with ampicillin Plasmid not taken up Plasmid taken up (WithoutBBW resistancegene) Plasmid taken up (WithBBW resistancegene) B) Outline how the genetically transformed bacteria containing the BBW resistance gene can beselected based on the amp and lacZgenes present within the plasmid.arrow_forward
