4 0

The structure of DNA is called a double helix because DNA is made up of two strands of nucleotides wound together in a spiral.

DNA has two strands that run opposite of each other and twist together much like a twisted ladder. Each backbone of the ladder is made up of alternating groups of sugar and phosphate groups.
