enzymes that function in breaking down dna do so by catalyzing the hydrolysis of covalent bonds that join nucleotides together. what would happen to dna molecules when treated with these enzymes? responses all bases would be separated from the deoxyribose sugar all bases would be separated from the deoxyribose sugar the two strands of the double helix will separate the two strands of the double helix will separate the sugar phosphate backbone of dna strands would be broken the sugar phosphate backbone of dna strands would be broken the pyrimidines would be separated from the deoxyribose sugar the pyrimidines would be separated from the deoxyribose sugar
