The process of turning genes on and off is known as gene regulation. ... Genes are turned on and off in different patterns during development to make a brain cell look and act different from a liver cell or a muscle cell, for example. Gene regulation also allows cells to react quickly to changes in their environments.

Answer:
The short answer is YES.
Explanation:
Theories can expand and change over time. This is how theories are developed, by collection of data and continued testing throughout time. As new technology develops, new discoveries are made. The same goes for the cell theory. Because of the limits of the previous microscopes, Robert Hooke was able to observe that cells were like cells of monks (little rooms) and thus named as such. As the microscope developed, they were soon able to determine the different organelles of the cell. Technology continued to developed and it helped determine that cells held hereditary material and so on and so forth.
