Answer:

Double helix structure

Step-by-step explanation:

The DNA is composed of two strands which are linked together by hydrogen bond. The two strands are twisted around each other to form a ladder-like, double helix structure.

The structure of the DNA was proposed by Watson and Crick after series of research about the nature and structure of the DNA.
