In separating DNA for genomic analysis, do scientists need to consider RNA contamination during the cell lysis step of a DNA extraction? a) yes, because DNA will combine with RNA

b) no, because DNA separates the supernatant

c) yes, because the protease destroys the DNA

d) no, because the RNA does not affect the DNA
