Assume you have isolated S.aureus from your skin. Design an experiment on how would you determine whether it is penicillin and erythromycin resistant? (Make sure to include a hypothesis and how you would design the experiment. Also include proper controls and discuss briefly the techniques you would use). I need one page please.

In the tubular flowers of foxgloves, wild-type coloration is red while a mutation called white produces white flowers. Another mutation, called peloria, causes the flowers at the apex of the stem to be huge. Yet another mutation, called dwarf, affects stem length. You crossed a red-flowered plant (gene symbol, r) to a plant that is dwarf (gene symbol, d) and peloria (gene symbol, p). All of the F1 plants are tall with red, normal stem flowers. You cross an F1 plant back to the dwarf and peloria parent, and you see the 543 progeny shown in the chart.
Dwarf, peloria stem, white 172
Tall, peloria stem, red 56
White, Tall, normal term 48
Red, dwarf, normal stem 6
Red, dwarf, peloria stem 43
White, tall, peloria stem 5
Red, tall, normal stem 162
Dwarf, normal stem, white 51
1) Which alleles are dominant?
2) What were the genotypes of the parents in the original cross?
3) Draw a map showing the linkage relationships of these three loci(R, D, P)

What two important physical properties contribute to the viscosity of DNA?
How is DNA made non-viscous by mechanical shearing? Use a labeled diagram to show what happens to the molecular structure of the DNA.
How is DNA made non-viscous by heating in a boiling water bath? Use a labeled diagram to show what happens to the molecular structure of the DNA.
Why is DNA in cells not viscous?
