Differentiation or specialization is a function that cells possess and is what allows them to have different types of cells and tissues.
Cell differentiation depends on genetic regulation, a mechanism that determines the specific genes that are expressed in a cell or tissue type.
All cells contain the same DNA, which is organized into chromosomes and contain the genes that determine specific characteristics. <u>There is cell differentiation because some genes can be expressed and others are suppressed, all due to genetic regulation</u>.
The other choices are wrong because:
- <em>The eyes look different from the liver, because they have the same genes, but only some are expressed.
</em>
- <em>Differentiated cells and tissues do not lose their genes.
</em>
- <em>All cells have DNA.</em>
