    Does "manual pouring" mean "pouring with hand"?


    WHEN I WAS A RESEARCH FELLOW IN GENETICS at Yale in the early 1980s, the determination of the actual
    sequence of several hundred letters of the DNA code was an arduous undertaking. The methods were finicky,
    requiring many preparative steps, the use of expensive and dangerous reagents such as radioactive chemicals, and the
    manual pouring of ultrathin gels that were nearly always plagued with bubbles and other imperfections. The details are
    unimportant; the point is, it took forever, with lots of trial and error, just to sort out a few hundred letters of the human DNA code.
