Question

The bases are held together in a DNA double helix by hydrogen bonds. These bonds are:​

Answer 1

Answer:

hydrogen. Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups (both within each component and between components). Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.

Answer 2

The bonds are covalent bonds.

Covalent and hydrogen bonds, two different types of bonding, hold the DNA double helix together.

Each linear thread has covalent bonds that firmly bind the bases, sugars, and phosphate groups together (both within each component and between components).

A base from one strand pairs complementary with a base from the other to form hydrogen bonds between the two strands. Although each of these hydrogen connections is weak, the group as a whole is fairly robust.
