Think of it as a ladder, being twisted.
You get a toy ladder and twist it repeatedly. You get the two spring like structure, going parallel to each other. DNA helix looks like the same.
DNA is organized in a double-helix fashion.
Both DNA and RNA can exist in the double helix form, but only DNA is completely stable as a double helix. The double helix RNA is usually only short "hairpin" sections folding back on itself, never the long essentially linear form of double helix DNA.
DNA is a double helix, or a twisted ladder.
They are helical in their structure; they look like a strand of DNA (the double helix.)
The enzyme Helicase unzips the DNA double helix
DNA, and the shape is also known as a double helix.
The name of the shape of DNA is called double helix. There are two long strands of DNA connected in several points. These strands twist and look like a spiral or a spring.
