5. Who was John Thomas Finch?John Thomas Finch was a British scientist who used X‑ray crystallography and electron microscopy to study the shapes of tiny biological parts like viruses and DNA.
6. What tools did he use to look at tiny things?He used X‑ray crystallography, which shines X‑rays on crystals to see how atoms are arranged, and electron microscopy, which uses a beam of electrons to make very detailed pictures.

X-ray crystallography: A technique that uses the diffraction of X-rays by a crystal to determine the atomic and molecular structure of the crystal.
Electron microscopy: A microscopy technique that uses a beam of electrons to produce a magnified image of a specimen, offering higher resolution than light microscopy.
Macromolecules: Large organic molecules, such as proteins, nucleic acids, carbohydrates, and lipids, that are essential for life and cellular function.
Nucleosomes: The fundamental structural units of chromatin in eukaryotes, composed of a segment of DNA wound around eight histone protein cores.
