Document Summary
Introduction to the study of call and molecular biology. The study of cells at the microscopic and molecular level. Molecular biology is reductionist it is based on the view that knowledge of the parts of the whole can explain the character of the whole. Our feeling for the wonder and mystery of life can be replaced by the need to explain everything i(cid:374) ter(cid:373)s of (cid:862)(cid:373)a(cid:272)hi(cid:374)er(cid:455)(cid:863) of the li(cid:448)i(cid:374)g s(cid:455)ste(cid:373) Cells can only be observed with the aid of the microscope provides magnified image by bending light.
