A double helix.
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules. The DNA segments that carry genetic information are called genes,
The duo of James D. Watson and Francis Crick discovered the structure of the DNA molecule in 1953, for which they were awarded the 1962 Nobel Prize award, along with Maurice Wilkins.
Their work became the basis for the Human Genome Project. Watson went on to head the Cold Spring Harbor Research Facility raising major funds for basic science research. Dr. Watson was noted for administrative successes and named to the head of the Human Genome Project.

All DNA are single stranded and long. Like rope.
In human body, DNA are double stranded. Due to forces of attraction between molecules, the DNA are coiled in such a way that is a helix shape.
Single stranded DNA and other forms are single-stranded and long.

the shape of DNA is a double-helix. in which it has an antiparallel and it goes from 5' to 3' direction.

Oddly enough, no one has made the obvious distinction of what a "Double Helix" actually looks like...
Think of a Double Helix as the hand rails of a spiral staircase. Both of them the same distance apart, and both spiraling at the same rate, never overlapping.
Hope that helps!

a double helix, very much like a twisted ladder, where the backbone of the ladder woud be the bonded sugar(deoxyribose)-phosphate chains and the "rungs" are the nitrogen based nuclotides (adenine, cytosine, guanine, and thymine) which are bonded by hydrogen bonds. (Note, the sugar phosphate bonds alternate as one goes up the ladder, but is opposite on the opposite side of the molecule, in other words, if one side of the backbone starts out with a sugar end and ends with a phosphate end the other strand must be facing "downward" therefore starting with a phosphate and ending with a sugar end.)
