A Gallery of Workers

big picture

The picture compares the sizes of the four workers mentioned in Life's Big Instruction Book: in the top row are Alcohol Dehydrogenase I (Al) and Aldehyde Dehydrogenase (Al's teammate); in the bottom row are a histone complex (the Instruction Book's spine) and the Lac repressor (tests for the taste of milk sugar). Al and Aldehyde Dehydrogenase are enzymes -- they perform molecular origami for a living. The other two cling to DNA -- histones all the time and the Lac repressor most of the time.
