Question

2 multiple choice 1 point why were rna molecules not spooled with the dna? rna was destroyed by ethanol rna is found only in animal cells rna was filtered out by cheesecloth rna is smaller and remains soluble in ethanol clear my selection

Explanation:

RNA molecules are smaller than DNA. During DNA - extraction using ethanol precipitation, DNA precipitates out while RNA remains soluble in ethanol due to its smaller size and other chemical - physical properties, thus not being spooled with DNA. Ethanol does not destroy RNA, RNA is present in both animal and plant cells, and cheesecloth is not used to specifically filter out RNA in DNA - extraction procedures.

Answer:

RNA is smaller and remains soluble in ethanol
