Question:
Who performed studies on a couple of restriction enzymes of the E. coli bacterium ?
Options:
Herbert Boyer.
Ramdeo Misra.
M.S. Swaminathan.
Francis Crick
Correct Answer:
Herbert Boyer.
Explanation:
In 1966, Boyer took over assistant professorship at the University of California at San Francisco. By 1969, he performed studies on a couple of restriction enzymes of the E. coli bacterium with especially useful properties. Boyer observed that these enzymes have the capability of cutting DNA strands in a particular fashion, which left what has became known as ‘sticky ends’ on the strands. These clipped ends made pasting together pieces of DNA a precise exercise.
