Hi pandagamer12
DNA is double-stranded so it is two strands that coil around each other. Do you mean how long is the DNA in the body? This is a really great website that describes things like this http://www.yourgenome.org/
Each cell contains 23 pairs of chromosomes and each chromosome is made up of a super-long pair of DNA strands coiled around each other. There are about 15 trillion cells in our bodies, so that is a lot of DNA strands.
When we look at DNA strands, we are often interested in the genes which code for proteins. Those can be found on either strand of DNA.
