deoxyribose linked to phosphate are correctly paired for the ladder analogy .
Option B is correct
In the ladder analogy, the deoxyribose and phosphate molecules form the backbone of the ladder, while the nitrogenous bases form the rungs of the ladder.
Nitrogenous bases linked together is incorrect because nitrogenous bases are not linked together as they are linked to deoxyribose molecules.
Deoxyribose linked to sulfate is incorrect because sulfate is not found in DNA. DNA is made up of deoxyribose, phosphate, and nitrogenous bases. In conclusion, hydrogen bonds do not form the rungs of the ladder as they hold the nitrogenous bases together.
complete question:
In the comparison of a DNA molecule to a twisted ladder, Which are correctly paired for the ladder analogy ? A) nitrogenous bases linked together. B) deoxyribose linked to phosphate. C) deoxyribose linked to sulfate. D) nitrogenous bases linked to phosphate. E) hydrogen bonds between bases.
