Q: Which of the following is a characteristic of the double helix structure of DNA?

Solution: The double helix structure of DNA features two antiparallel strands that are held together by hydrogen bonds between complementary bases.

Steps: 5

Step 1: Understand that DNA is made up of two long strands.
Step 2: Know that these strands twist around each other to form a shape called a double helix.
Step 3: Learn that the strands run in opposite directions, which is called 'antiparallel'.
Step 4: Recognize that the strands are connected by weak bonds called hydrogen bonds.
Step 5: Identify that these bonds form between specific pairs of bases (A with T and C with G), which are known as complementary bases.
