What kind of bond holds the two strands of a DNA molecule together?
hydrogen bonds. The other bonds are covalent bonds.
Why is it advantageous to have weak hydrogen bonds between complementary base pairs and strong covalent bonds between phosphate and deoxyribose groups in a DNA molecule?
The reason why it is advantageous to have weak hydrogen bonds between complementary base pairs and strong covalent bonds between phoshate and deoxyribose groups in a DNA molecule is because the strong covalent bonds running along the "ladder" of the DNA molecule (the phospate and deoxyribose units) keep the molecule together during its existence and more importantly its reproduction. The weak hydrogen bonds in the middle keep the reproduction cycle going on forever because it is able to perform an easy split between the hydrogen bonds throughout the middle of the molecule.
Is DNA a covalent or is it an ionic bond?
Covalent as well as weak hydrogen bonds
What breaks covalent bonds in DNA backbone?
Topoisomerase
What molecule catalyzes covalent bond formation between DNA?
DNA ligase

Which enzyme is responsible for creating the covalent bonds that connect the sugar-phosphate backbone of the new DNA molecule?
DNA ligase

What connects the backbone of the DNA molecule together?
The DNA backbone is made of phosphate group and deoxyribose, and they are held together by covalent bonding.
What type of chemical bond holds together the backbone of a strand of DNA?
Covalent bonds between a sugar molecule (deoxyribose) and a phosphate group make up the backbone of DNA. These are very strong covalent bonds and are broken only with great expenditure of energy--x-rays, for example.
What type of bond connects to the backbone of a DNA molecule?
The nucleotides are linked by peptide bonds - covalent bonds between the carbon in the carboxyl group and the nitrogen in the amino group. The double helix is formed by hydrogen bonds between the hydrogens and oxygens of two strands of nucleotides.

Covalent as well as weak hydrogen bonds

Topoisomerase
What molecule catalyzes covalent bond formation between DNA?
DNA ligase
Why does a double stranded molecule denature into two single stranded molecules when heated?
The heat breaks the hydrogen bonds that hold the nitrogenous bases together in the centre of the DNA molecule. However, the covalent bonds between the phosphate and deoxyribose sugar are not affected.
What makes up the sides of the ladder a DNA molecule?
The backbone of the DNA molecule is made up of a sugar (deoxyribose) bonded to a phosphate group bonded to another sugar and then another phosphate and so on. These are very strong covalent bonds that are not easily broken.
