Question

9 multiple choice 1 point what role did the detergent (sds) in the homogenizing solution play? it precipitated dna it cooled the solution it stained the dna it broke open cell and nuclear membranes clear my selection

Explanation:

SDS (sodium - dodecyl sulfate) is a strong anionic detergent. In DNA extraction procedures, it disrupts cell and nuclear membranes by interacting with the lipid - protein components of the membranes, allowing the release of DNA into the solution. It does not precipitate DNA, cool the solution, or stain DNA.

Answer:

It broke open cell and nuclear membranes
