question 2 of 9
during the salting step of dna extraction, the sample is treated with a concentrated salt
solution to clump the _ released by the lysis of membranes.
lipids and proteins
sugars and starches
nucleotides
enzymes

Explanation:

During DNA extraction, the salting step uses a concentrated salt solution. Lipids and proteins are released by membrane lysis. Salt causes these to clump (precipitate), allowing DNA to be separated. Nucleotides are part of DNA structure (not clumped here). Sugars/starch and enzymes are not the main components clumped in this salting step for DNA extraction.

Answer:

lipids and proteins
