The right answer is True.
In multicellular organisms the expression of different genes is at the origin of a cellular specialization. In humans, there are 250 different types of cells because of their morphology, their biochemistry and their role in the body.
The expression of eukaryotic genes is regulated by several mechanisms (activator or inhibitors) at the chromatin level, at the transcriptional level, at the post-transcriptional level, at the translational level and at the post-translational level.
