Question

Detailed structure of the membrane was studied after the advent of electron microscope during

• A. $1930$s
• B. $1950$s
• C. $1970$s
• D. $1990$s

Answer 1

The correct option is B $1950$s

Electron microscopy (EM) is a technique for obtaining high resolution images of biological and non-biological specimens. It is used in biomedical research to investigate the detailed structure of tissues, cells, organelles and macromolecular complexes. Electron microscope was discovered in 1931 and after its discovery structure of membrane was studied. So, we can assume that the study of membrane structure was done during 1950s.

So, the correct option is B.
