CORRECT WELL DETAILED ANSWERS|LATEST
What is the cell theory? - ANSWER All living things are made up of cells, cells are the
basic units of structure and function in living things, new cells are produced from existing
cells
What is cytology? - ANSWER study of cell structure
What is biochemistry? - ANSWER focuses on cellular structure and its functions
What is genetics? - ANSWER the study of heredity and the variation of inherited
characteristics.

structures of molecules
What is X-Ray crystallography? - ANSWER technique used to determine the 3D
structure of a molecule
to do it, purified samples of DNA are crystallized and bombarded X-rays
