Nucleotide arrangement in DNA can be seen by

1. X-ray crystallography
2. electron microscope
3. ultracentrifuge
4. light microscope

Correct answer: X-ray crystallography

Solution

X-ray crystallography is used to determine the three-dimensional arrangement of atoms in molecules like DNA by interpreting diffraction patterns. The other instruments listed do not provide this level of structural detail for nucleotide arrangement.
