what is the structure of the dna molecule?
a single helix
b double helix
c alpha helix

Explanation:

The structure of the DNA molecule is a double helix. This is a well - established fact in biology, where DNA consists of two strands that wind around each other in a helical structure. The "Single helix" is incorrect as DNA has two strands, and the "Alpha helix" is a structure found in some proteins, not DNA.

Answer:

b. Double helix
