Length of uncoiled DNA?

From which chromsome? A nucleotide within a helix occupies roughly 3.4 Å or 0.34 nm (am not 100% sure but should be easy to check). If we made a single molecule out of all chromosomes, the haploid genome (about 3 gigabases) would have roughly the length of 1m. This is assuming that it still maintains a helical structure.

"Getting confused, you mean the DNA in the body varies with specialized cell?"

"helical structure" what i'm trying to get is the length of the DNA uncoiled, unwined and stretch to the maximum length. Is this known? <not assuming it to be in helical structure>.
