    According to another study, when measured in a different solution, the DNA chain measured 22–26 Å (2.22.6 nm) wide, and one nucleotide unit measured 3.3 Å (0.33 nm) long. [10] The buoyant density of most DNA is 1.7g/cm 3. [11] DNA does not usually exist as a single strand, but instead as a pair of strands that are held tightly together.
