A 2.0kb bacterial plasmid ‘BS1030’ is digested with the restriction endonuclease Sau3A; the plasmid map is depicted in the diagram below and the Sau3A (S) restriction sites are indicated. Which of the following DNA fragments do you expect to see on an agarose gel when you run Sau3A-digested plasmid ‘BS1030’ DNA? a. 250 bp, 450 bp, 550 bp, 1.1 kb, 1.5 kb and 2.0 kb b. 2.0kb c. 250 bp, 400 bp, 450 bp, 500 bp and 550 bp d. 100 bp, 200 bp, 250 bp, 400 bp, 500 bp and 550 bp
Refer to the diagram of pUC18 (Fig.) to determine which restriction enzymes you could use to insert a gene that would interfere with production of β-galactosidase by the host cell.
The total size of the plasmid is 2686 bp. There is a PstI recognition site at position 439, HindIII recognition site at position 447, and ScaI recognition site at 2179. If restriction enzymes ScaI and HindIII are used to cut this plasmid, what would be produced? a. 2 fragments: 954bp and 1732bp b. none of the choices apply c. 1 linear fragment of 2686bp d. 3 fragments: 447bp, 507bp and 1732bp
How does the insertional inactivation ofb-galactosidase allow the presence of foreign DNAin a plasmid vector such as pUC19 to be detected?
U have the plasmid pUC18/19, which is a circular plasmid that consists of 2686 bp. What would the number of and length of the fragments be if you cut the plasmid with the following restriction enzymes or combination of enzymes? Give a schematic representation of the digestions.

After digesting the DNA produced by PCR (generated using the primers mentioned in question 2 added for context below) and the pET-28a vector with restriction enzymes SacI and HindIII, what steps would be needed to obtain a pure culture of E. coli cells that contain the pET-28a-OXA-M290 plasmid (i.e., a culture which consists only of E. coli cells that contain this plasmid)? And, how could you confirm that the OXA-M290 gene was successfully cloned into the pET-28a vector without any mutations? [4 – 8 sentences suggested] Question 2 (Do not answer, just for context):The forward primer that will be designed is the primer that binds to the region of the OXA-M290 gene where the start codon is located, and the reverse primer is the primer that binds to the region of the gene where the stop codon is located. In order to clone the PCR product generated using these primers into pET-28a, extra nucleotides must be added to the 5' ends of the primers. These extra nucleotides will contain the…
Below is a map of the E. coli cloning vector after the insertion of pka-1. Ori denotes the origin of replication; amp denotes the ampicillin resistance gene. HindIII, BamHI, SalI, and EcoRI designate restriction enzyme sites. There are no other restriction enzyme sites found on this vector. The numerals denote the number of base pairs between different locations on the plasmid. For instance, there are 400 base pairs between the HindIII and BamHI site, and there are 3000 base pairs in the entire cloning vector (following the integration of pka-1). With the use of well-illustrated diagrams, reconstruct the entire cloning process by explaining different stages of the cloning process that involves the following: Isolation of target DNA fragments (often referred to as inserts) Ligation of inserts into the plasmid, creating recombinant molecules Transformation of recombinant plasmids into bacteria or other suitable host for propagation Screening/selection of hosts containing the intended…
Give the recognition sequences for each of the restriction enzymes (a) PagI, (b) AluI, (c) PstI, and (d) RcaI. Show the sequence in double-stranded DNA (dsDNA) format, indicate the cleavage position with a ^, and mention which types of ends are generated in each case (blunt or sticky; 5’ or 3’ overhang)? Recognition sequence for a)PagI cleaves DNA at the recognition sequence 5' ---T ^CATGA--- 3' b) AluI cleaves DNA at the recognition sequence 5' AG^CT 3' c) PstI cleaves DNA at the recog.
If restriction endonucleases are produced by bacteria within a host, why don’t these enzymes chew up the genomic DNA of their host? What is the role of DNA methyltransferase in this?
