List 3 similarities in how DNA is isolated from bacteria and from yeast.

Expert Solution

The first step in both the processes is the removal of cell wall. The cell wall is made up of peptidoglycan in bacteria and of glucan and mannons in yeast. The cell wall is broken down in both the cases.

II similarity is that won the cell wall is removed, plasma membrane is broken down in both the cells. Plasma membrane breakdown is important for the exposure of cytoplasmic content in both the cells.

The last step is also common in both the cells because it involves precipitation of DNA molecules using chilled ethanol. DNA is present in solubilzed form in aqueous phase and is precipitated out by the addition of chilled ethanol.

(Note - differences in the isolation of DNA from cell occur because different cells have different structure and composition, but the principal for the extraction of DNA remain the same for the types of cells).

A third haploid pink strain (strain # 3) of yeast is isolated and known to be the MAT a sex. Nothing else is known about this strain, (i.e. we do not know whether it is a single or double mutant as we did in our lab results). When streaked together with strain #1 above the cells produced at the crossing juncture are all pink. Answer these questions: a) Would you expect these pink cells at the strain 1-3 crossing juncture...

Isolated naked bacterial DNA from which proteins are removed is supercoiled. DNA in bacterial chromosomes is also supercoiled. When naked DNA is nicked, supercoiling is abolished. In contrast nickling chromosomal DNA does not abolish supercoiling. Why?

If you were to replace the DNA-binding domain of the Yeast Gal4 protein with the DNA binding domain from the Lac repressor, this protein would no longer regulate the transcription of GAL genes in yeast. A: Draw two different modular diagrams (just pairs of labeled rectangles of domains) of the different functional domains you would expect to find in the Gal4 protein and in the engineered protein. B: Why does the engineered protein no longer regulate transcription of the GAL...
