The flagella and pili are similar in that they are both composed of proteins. <span>Flagella is made up of protein flagellin, while pili is composed of protein pilin.

Dorothy Mary Crowfoot Hodgkin was the first to develop protein crystallography and she won Nobel Prize for that discovery ( third woman to win the Nobel Prize in Chemistry). Hodgkin confirmed the structure of penicillin but also realized the structure of vitamin B12 by x-ray crystallography analysis. She advanced the classical technique of X-ray crystallography.
