A white pellicle or precipitate appears when the lysozyme/SDS solution is treated with sodium acetate. What does the pellicle contain?
Homework Answers
Treatment of the lysozyme solutions with sds causes the solution to clarify and become viscous.Sds disrupts the cell membrane and denatures protein.In addition to lysing the cells, alkaline sds denatures the cellular constituents and it's elevated pH begins to degrade the cellular RNA.
On adding K-acetate to reanneal plasmid and DNA, plasmid is small so it can be reanneal faster, but DNA is too long to reanneal so it's gets targeted, DNA gets made into pellet, plasmid loats in supernatant, so a white pellicle or precipate appears when the lysozyme /sds solution is treated with sodium acetate.

2.When concentrated H2SO4 (18M) is added to a saturated solution of sodium sulfate, a white precipitate is formed. Write a net-ionic equation for the equilibrium in saturated sodium sulfate, and explain the change in terms of Le Chatelier’s principle. 3.A solution contains the blood-red hexathiocyanatoferrate(III) complex ion, Fe(SCN)63-, in equilibrium with the iron(III) ion, Fe3+, and six thiocyanate ions, SCN-. If the solution is diluted with water, will the color deepen, fade, or stay the same? Why? In addition to...

Why would magnesium sulfate is give the same result (white precipitate) in the Phosphate ion test as zinc acetate? The control procedure was 2mL of .1M zinc acetate with 2 mL sodium phosphate tribasic in a test tube. Yields a white suspended precipitate immediately. The experiment was a mixture of the same sodium solution and 2mL of unknown liquid this yielded the same result immediately. I then tried to confirm my guess of the unknown liquid as magnesium sulfate by...
