-PBR322 DNA (4.32 kb) was cleaved with HindIII nuclease and lig-ated to a HindlII digest of human mitochondrial DNA. One recom-binant plasmid DNA was analyzed by gel electrophoresis of restric-tion cleavage fragments, with the following results: lane A =EcoRI-treated recombinant, lane B= HindIII-treated vector, andlane C= HindlII-treated recombinant.AB6.62 kb4.32 kb1.15 kb (a) Why was the recombinant plasmid treated with EcoRI for deter-mination of its size?(b) How might you explain the discrepancy between the size of therecombinant molecule and the sum of the sizes of the HindlII cleav-age fragments?(c) Draw a diagram of the recombinant showing the locations of theHindlII cleavage sites.

You receive purified mRNA that codes for the spike protein of SARS-CoV-2 as well as plasmid pET32(a+). Explain how you will prepare SARS-CoV-2 spike cDNA and name the enzymes that you will need how you will clone the cDNA into pET32(a+) and select the recombinant plasmid how you will then produce a recombinant SARS-CoV-2 spike and purify it
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
Match the following Conjugation terms with the most appropriate description in the image: F- recombinant F- strain F+ strain HFR strain
A PCR reaction was performed to amplify the XULA4 gene, which is bp 524-6,480 on a plasmid that is 9,435 bp. After the PCR, the product was digested with XhoI. There are XhoI sites on the plasmid at bp 151, 1,336, and 4,795. Calculate the size(s) that would result when the product is digested with XhoI. Then enter the size of the largest fragment (in bp).
Homologous recombination in E. coli forms heteroduplex regions of DNA containing mismatched bases. Why are these mismatches not eliminated by the mismatch repair system?
Clone number in this case is number 196 which is shown in the images. State whether a BamHI site has been re-created at the forward- and the reverse-end junctions of the human DNA with the plasmid vector band sizes are shown in one of the images. (0.5, 1, 2, 3, 4, 5, 6, 8, 10kb)
It is possible to "reconstitute" nucleosomes by mixing DNA and his- tone octamers in 2M NaCl and then dialyzing to low salt. When such experiments were carried out using a specific 208-bp fragment of sea urchin DNA, the following results were obtained: Digestion of the product with micrococcal nuclease gave quantitative production of 146-bp DNA. Upon cleavage of this DNA with a restriction nucle- ase having a single site in the fragment, several sharp bands were obtained, with sizes as follows: 29 bp, 39 bp, 107 bp, 117 bp. How would you interpret these data in terms of nucleosome positioning on this DNA?
None
2c) If the whole potoroo genome is 4.2 x 10' bp, and the highlyrepetitive DNA in the potoroo genome is composed entirely ofcopies of the sequence 5'AAGACT' and its complement, howmany copies of this sequence are present in the potoroogenome?
The nucleosome assembly factor exclusively functions in DNA-dependent nucleosome assembly and binds to the PCNA (clamp) of DNA polymerase. (Capitalization and dashes/spaces are not critical.)
a.) wanting to clone gene Z into pVector, the gene is amplified by PCR and restriction sites are added to the flanking ends. without realizing that the antibotic resistant gen )tetR) had a Sal1 site, you decide to add EcoR1 and Sal1 recofnition sequencen into the 12-nucleotide primers. Write the sequence of the 2 primers, noting the 5' and 3' ends?
Genomic DNA from a family where sickle-cell disease is known to be hereditary, is digested with the restriction enzyme MstII and run in a Southern Blot. The blot is hybridised with two different 0.6 kb probes, both probes (indicated in red in the diagram below) are specific for the β-globin gene (indicated as grey arrow on the diagram below). The normal wild-type βA allele contains an MstII restriction site indicated with the asterisk (*) in the diagram below; in the mutated sickle-cell βS allele this restriction site has been lost. What size bands would you expect to see on the Southern blots using probe 1 and probe 2 for an individual with sickle cell disease (have 2 βS alleles)? Probe 1 Probe 2 (a) 0.6kb 0.6kb and 1.2kb (b) 0.6kb and 1.8kb 0.6kb, 1.2kb and 1.8kb (c) 1.2kb 0.6kb (d) 1.8kb 1.8kb a. (a) b. (b) c. (c) d. (d)
