Why is it important to create a restriction map/ vector map?
Step by step
Solved in 2 steps
- Which of the following sequences, in the double-stranded form, can probably be recognized by a restriction enzyme? Choose an answer from below? TTCCTT CGACGA GTCGAC GGTTGG GAGGACDraw a diagram/figure to explain the conjugation process (e.g. use PowerPoint or draw one by hand and include a photo of it). You should include in the diagram the F- recipient, Hfr Donor and the transconjugant/recombinant recipient. Make sure to include the genes encoding for Leucine, Threonine, Thiamine and Streptomycin resistance in your diagram. How does an Hfr strain of coli transfers chromosomal DNA to an F- strain? What determines how much of the chromosomal DNA is transferred?Why is Agrobacterium mediated genetic transformation described as Natural Genetic engineering in plants?
- Lane 5 in the gel above displays the pBashi cleavage products after restriction digest with the restriction enzymes Xhol+ Pstl. Lane 6 in the gel above displays the pBashi cleavage products after restriction digest with the restriction enzymes Xhol+ HindlII+ Pstl. label on the plasmid. i) The location of the Pstl site ii) The sizes of the new fragments made by this Pstl cutThe figure below shows a partial chromosome map of an E. coli Hfr strain. Each mark = 10 minutes between conjugation transfer time. If transfer of genes begins at “*” relative to the origin of transfer, what is one of the predicted results from this map? It would take less than 30 minutes to transfer all of the genes that are shown. gal and azi will rarely be transferred together. gal and ton will rarely be transferred together. Ten minutes after transfer of ton, lac will be transferred. This strain will produce very few gal recombinants.For a restriction enzyme that recognizes the restriction site GGCC, Which of the following statements is/are true?
- 2a) With the aid of diagrams, describe the critical role of restriction enzymes in genetic engineering? b) Write short notes on any two characteristics of a vectorIn the genotype presented (genomic plus plasmid genes), which of the following statements Is phenotype? genome: IS P O`z+Y° plasmid: I* Pt otzY+ no production of either B-gal and permease O B-gal and permease induced when lactose is present no B-gal is produced and expression of permease when lactose is present constitutive expression of B-gal and permease constitutive expression of B-gal and no expression of permeaseWhat is the process called when bacteria exchange small pieces of DNA called plasmids or vectors that contain antibiotic resistant genes.
