Correct Answer: Hydrogen bonds

Solution:

Hydrogen bonds between complementary nitrogenous bases hold the two strands of DNA together.

What type of bond holds the two strands of DNA together?

What type of bond holds the two strands of DNA together?

Step 1: Understand that DNA is made of two strands that twist together to form a double helix.
Step 2: Know that each strand of DNA is made up of smaller units called nucleotides.
Step 3: Recognize that nucleotides contain nitrogenous bases (A, T, C, G).
Step 4: Learn that certain bases pair together: Adenine (A) pairs with Thymine (T), and Cytosine (C) pairs with Guanine (G).
Step 5: Understand that the pairs of bases from each strand are held together by weak attractions called hydrogen bonds.
Step 6: Conclude that these hydrogen bonds between the complementary nitrogenous bases are what hold the two strands of DNA together.
