Question

Quizplus · Accepted Answer

The bonds that hold DNA and RNA backbones together are known as 3'-5'-phosphodiester linkages. These linkages involve the connecting of the 3' carbon of one nucleotide to the 5' carbon of another nucleotide through a phosphate group. Choice A is incorrect because it incorrectly lists the positions of the carbons involved. Choice C is incorrect because it refers to a different type of chemical bond. Choice D is incorrect because it refers to the bond between the sugar and nitrogenous base of a nucleotide, not the bond between nucleotides in the backbone. Choice E is incorrect because it refers to a bond found in proteins, not nucleic acids.
