That happens to be the shape formed when the two strands are electrostatically bonded and is due to the arrangement of atoms, the number of bond- and lone-pairs of electrons, the bond lengths and the number of covalent bonds they each have.
yes
Yes.
double helix
DNA, and the shape is also known as a double helix.
The whole DNA strand is a double helix.
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.
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.
DNA is organized in a double-helix fashion.

The enzyme Helicase unzips the DNA double helix
In the DNA. The term "double helix" refers to the structure of DNA.
A DNA strand is shaped like a 'double helix'.
