Elaborate on the idea that proteins are the workhorse molecules of the cell. What will be an ideal response?
ANSWER: Proteins perform tasks essential for life; they form most of the structures in a cell, transfer
energy to drive all processes in a living cell, help copy chromosomes for cell division, control
which genes are switched on and off, relay signals, fight infection, and repair damage caused
by environmental agents. All of these protein functions result in the production ofphenotypes.
