Strands of DNA are joined byMultiple Choicehydrogen bonds.covalent bonds.ionic bonds.phosphodiester bonds.

The two strands of DNA are held together by __________Group of answer choiceshydrogen bondspeptide bondsnitrogen bondsglycosidic linkage

The pairing of complementary bases in DNA (through hydrogen bonding) means that the information contained within each strand is redundant. Phosphodiester (intra-strand) bonds are stronger than hydrogen (inter-strand) bonds. The actual job of the phosphodiester bonds is where in DNA polymers connect the 5' carbon atom of one nucleotide to the 3' carbon atom of another nucleotide, while the hydrogen bonds stabilize DNA double helices across the helix axis but not in the direction of the axis.[19] This makes it possible to separate the strands from one another. The nucleotides on a single strand can therefore be used to reconstruct nucleotides on a newly synthesized partner strand.[20]

In DNA, Thymine and Adenine on two complementary strands are bonded together by ___________Group of answer choicesTwo Hydrogen bondsS-S covalent bondsThree Hydrogen bondsFour Hydrogen bonds

The weak chemical bonds important in holding the DNA double helix together is the: ionic bond polar covalent nonpolar covalent hydrogen bond

DNA is constructed ofGroup of answer choicesa single strand of nucleotides with internal hydrogen bonding.two complementary strands of nucleotides bonded A—C and G—T.two strands of nucleotides running antiparallel.two strands of identical nucleotides with hydrogen bonds between them.None of the answers is correct.
