Decide on two restriction sites that you can use to clone this into pL4440’s MCS. Identify their sequence and explain why. Tip: The plasmid map is showed below, details of restriction site sequences can be found at https://enzymefinder.neb.com/#!#nebheader

In regards to using PCR: Explain why a plasmid is often engineered with tetR and lacZ. What purpose do they serve?

true or false if a restriction enzyme recognizes the restriction site, 5' AACGTT3', and the enzyme cuts between the second A and the C, this will produce a "sticky end," which is useful for cloning into a plasmid vector.

A biologist is attempting to clone the gene encoding a particular enzyme (Enz) into a plasmid vector in E.coli. This plasmid has a gene encoding a green fluorescent protein (GFP) as well as a gene for tetracycline antibiotic resistance (TetR). The restriction site (to clone foreign DNA into) is within the GFP sequence. Which of the following would be expected when trying to see which E. coli cells acquired the recombinant plasmid (i.e., carrying the Enz gene)?     Bacteria UNABLE to grow on tetracycline-containing media AND are NOT able to make green fluorescent protein are the ones that contain the recombinant plasmid.     Bacteria able to grow on tetracycline-containing media AND that are NOT able to make green fluorescent protein are the ones that contain the recombinant plasmid.     Bacteria able to grow on tetracycline-containing media AND are able to make green fluorescent protein are the ones that contain the recombinant plasmid.     Bacteria UNABLE to…

You have another circular plasmid. Complete and effective digestion of this plasmid with a restriction enzyme yields three bands: 4kb, 2kb, and 1 kb. In comparing the band intensity on an ethidium bromide-stained gel, you notice that the 4 kb and the 2 kb bands have the exact same brightness. The 1 kb band is exactly one fourth as bright as each of these. (Assume there is uniform staining with ethidium bromide throughout the gel.) How many times did the enzyme cut the plasmid? What is the size of the plasmid? Justify your answers to a and b above using a clearly labeled diagram showing the relative location of the cut-sites on the plasmid.

When performing cloning experiments, it is not always necessary to treat sources of DNA with the same restriction enzyme. For example, DNA treated with EcoRI can be combined with DNA from a treatment using FunII. Explain why this is possible.

You utilised two plasmids in this practical, pOTC and pOTC-Δ. Plasmids are often represented using plasmid maps like the one below. This map shows the positions of recognition sites for a number of restriction enzymes Using the plasmid map of pBCH2.0 provided above, predict how many DNA fragments would be formed if this plasmid was digested with restriction enzymes EcoRI and PvuII.

please help me with this problem

Please look at the picture. Thanks
