Summary Introduction
To determine:
The region at which the centromeric DNA is located.
Introduction:
A scientist conducted experiments by using the DNA of yeast centromere. In this experiment, the yeast centromere DNA was cloned in the YRP7 plasmid. The insertion of this DNA into the plasmid makes the plasmid

When cloning a foreign DNA fragment into a plasmid, it is often useful to insert the fragment at a site that interrupts a selectable marker(such as the tetracycline-resistance gene of pBR322). The loss of function of the interrupted gene can be used to identify clones containing recombinant plasmids with foreign DNA. With a yeast artificial chromosome (YAC) vector, it is not necessary to do this; the researcher can still distinguish vectors that incorporate large foreign DNA fragments from those that do not. How are these recombinant vectors identified?
A shuttle vector is a vector (usually a plasmid) constructed so that it can propagate in two
different host species. One of the most common types of shuttle vectors is the yeast shuttle
vector. Examples of such vectors derived from yeast are Yeast Episomal Plasmid (YEp), Yeast
Integrating Plasmid (YIp) and Yeast Replicating Plasmid (YRp). Among these three vectors,
YIp has the lowest transformation frequency and copy number per cell. Explain why Ylp is still
popularly used despite its limitations.
It is desired to isolate genomic DNA from liquid culture of S. cerevisiae yeast. A commercial kit will be used to isolate genomic DNA from this liquid culture. Answer the following questions to understand the strategy used by commercial kits for genomic DNA isolation.
a) List all the steps from cell pellet preparation to DNA elution.
b) With which feature can the membrane in the column that comes with the commercial kit bind DNA?
c) Which component in the kit would you use to recover the DNA from the membrane of the column to which the DNA was attached?

- Many resistance mechanisms are encoded on plasmids. These mechanisms are of great clinical significance, because they can spread very easily through horizontal gene transfer. A culture of the bacterial isolate is grown, and plasmid DNA is isolated using a spin column-based solid phase extraction method. The purified plasmid DNA is then submitted for next-generation sequencing. Bioinformatic analyses of the sequencing results suggests that the following gene is likely involved in antibiotic resistance: > putative antibiotic resistance gene ATGCGTGTATTAGCCTTATCGGCTGTGTTTTTGGTGGCATCGATT ATCGGAATGCCTGCGGTAGCAAAGGAATGGCAAGAAAACAAAAGT TGGAATGCTCACTTTACTGAACATAAATCACAGGGCGTAGTTGTG CTCTGGAATGAGAATAAGCAGCAAGGATTTACCAATAATCTTAAA CGGGCGAACCAAGCATTTTTACCCGCATCTAGTGCGAAAATTCCC AATAGCTTGATCGCCCTCGATTTGGGCGTGGTTAAGGATGAACAC CAAGTCTTTAAGTGGGATGGACAGACGCGCGATATCGCCACTTGG AATCGCGATCATAATCTAATCACCGCGATGAAATATTCAGTTGTG CCTGTTTATCAAGAATTTGCCCGCCAAATTGGCGAGGCACGTATG…arrow_forwardA plasmid that is both ampicillin and tetracyclineresistant is cleaved with PstI, which cleaves within theampicillin resistance gene.
