Question
Chapter 17, Problem 14TYK
Summary Introduction
To review:
The experiment that can confirm the presence of a wild type bio+ allele in the plasmid of chromosomal DNA (deoxyribonucleic acid).
Introduction:
Minimal media is the media that only provides minimum requirement that is only inorganic salts and no amino acids. The colonies whose genome is complete, that is, they have genes for all requirements grows on the minimal media while others do not.
Electroporation is the technique in which electric pulse is given to the culture leading the opening of the transient pores in the cells that can allow the entry of the DNA from the surrounding.

The Molecular Cell Biology Unit of University X is working on a particular gene segment called ABC20. For a specific kind of experiment, they need to quantify the gene and require a lot of copies of the gene. The initial gel run showed a very faint band of the gene which made the quantification process difficult to proceed. Now propose a method with the help of which they can generate many copies of the gene. Here you need to know that they have the plasmid from where they can get the gene. You do not need to explain the process in detail rather answer in no more than 10 sentences on what can be done about this problem!
When plasmids are isolated from bacterial cells, they may existin a number of forms.a. List the different forms that may be found.b. Which do you think would migrate the fastest and farthest in anelectrophoresis experiment and why?

plasmid?
O Bacteria containing the plasmid would be able to grow in the absence of ampicillin.
O Bacteria containing the plasmid would be able to grow in the presence of ampicillin.

- Scientists modified the tumor-inducing (Ti) plasmid, a naturally occurring plant plasmid found in Agrobacterium tumefaciens, to create a tool used to introduce any gene of interest into plant cells. They created a binary system because a single Ti plasmid is too large to be easily manipulated. One part of the system is a disarmed plasmid, and the second part is a transformation vector. The following sentences describe the function of key DNA elements in the system. Virulence region Genes for conjugative transfer Disarmed Ti plasmid (T-region removed) ori Kan selectable marker plant selectable marker constitutive promoter T-region conjugative transfer virulence Kan (bacterial selectable marker) Amp selectable marker Plant selectable marker (e.g., herbicide resistance) Constitutive promoter T-DNA left border Place the terms in the appropriate blanks to complete the sentences.

There is a restriction site within the strR gene that you are hoping to move your gene of interest into. After cutting both your vector and insert you mix them together in a test tube. You then transform your mixture into E. coli and plate your cells on a master plate without any antibiotics. After colonies appear, you pick and re-plate onto a streptomycin containing plate and onto a kanamycin containing plate. 1. Using those same pieces of short DNA that you created above, show me what one of them may look like if it was cut with a blunt end restriction endonuclease. With the other example, show me what it would look like if it was cut with a sticky end restriction endonuclease. 2. Why do restriction endonucleases exist in bacterial cells? What must they do to protect their own DNA?arrow_forwardA plasmid vector has two genes in it, a gene for streptomycin resistance (strR) and another for kanamycin resistance (kanR).

To study what genes might be affected, the mutant strains are cultured along with the normal parental strain at the permissive temperature (37°C) and then shifted at 10 minute intervals to the non permissive temperature (42°C). The only nucleotides in the growth environment are labeled with 32P. The amount of DNA at each step is measured by determining the amount of labeled nucleotides that have been incorporated into the DNA. The numbers refer to the relative amount of labeled nucleotides that have been incorporated. The following results are obtained.(picture) Which strains/strains, if any, has a mutation in a gene required for DNA replication? Explain your experimental predictions and the degree to which the data support/fail to support them.arrow_forward
- How would you determine if a transfection was transient or stable? This image might be helpfularrow_forwardA plasmid, pUC18, contains the ampicillin-resistance gene, the origin of replication, and the ß - gal gene, which codes for the B-galactosidase protein. This protein can break down the synthetic chemical X-gal, producing a blue product that stains the entire cell blue (but is harmless to the bacteria). At the beginning of the B-gal gene there are several unique restriction sites (some of them are shown in the diagram below). You wish to clone a 1.0-kb Xbal fragment into the pUC18 plasmid, so you cut the plasmid with Xbal and, after removing the enzyme, mix the Xbal-cut plasmid with the 1.0-kb fragment, ligate, and transform competent bacteria. Pati Xbal EcoRI B-gal A Amp ori Figure: pUC18 plasmid map (a) On what medium would you grow your transformed bacteria? (b) Do you expect the bacteria carrying plasmid pUC18 (without the insert) to be blue or white when grown in the presence of X-gal? Explain.arrow_forwardChoose the one answer that fits best. The pGLO plasmid you used contains an araC gene, a GFP gene and a bla gene. If you performed the exact same experiment with a plasmid that contained a GFP gene and a bla gene, but was missing the araC gene, what would you expect to see on your four plates? a. The positive control would not have any bacterial lawn b. The negative control would have as many colonies as the experimental plate c. The LB/Amp/Ara plate would have some colonies but they would not be fluorescent under UV light d. The experimental plate would not have any colonies e.
