Final answer:

Hydrogen bonds hold the two strands of a DNA molecule together through a double-helix structure.


Explanation:

Hydrogen bonds are what hold the two strands of a DNA molecule together. These hydrogen bonds connect the complementary base pairs across the two strands, creating the double-helix structure of DNA.

The hydrogen bonds in DNA play a crucial role in maintaining the overall structure of the molecule, allowing for processes such as DNA replication and transcription to occur.

Compared to the covalent bonds within the DNA molecule, hydrogen bonds are relatively weak, which enables the strands to separate when necessary for cellular processes like replication.

Answer: A. Hydrogen bonds

Explanation:

Hydrogen bonds hold together the two strands of a DNA molecule together. They are held together in a double helix which is:

  • Adenine (A) pairs with Thymine (T)
  • Cytosine (C) pairs with Guanine (G)
