Answer: L (DNA) = 190.4 nm.

The DNA molecule is not only spiral, but also consists of two strands. To determine the length of a DNA fragment, you need to know the total number of nucleotides and the length of one nucleotide. The length of 1 NC is standard and is 034 nm. According to the condition of the problem, the amount of DNA is equal to: 560 * 2 = 1120. But you need to remember that the chains are opposite each other, which means the amount in this case does not affect the length. The length of the DNA is: 560 * 0.34 nm = 190.4 nm.
