Is it true or false that in a multicellular organism, cells with different functions have different DNA?

The statement is false because all cells in a multicellular organism contain the same DNA, which is the organism's complete genetic blueprint. This includes all the genes necessary for the development and functioning of the organism. While the DNA remains unchanged, different cell types express different subsets of these genes, leading to the diverse functions and characteristics of various cells, such as muscle cells, nerve cells, and skin cells. The process of gene expression allows cells to differentiate and perform specialized tasks while retaining the same genetic information.

In contrast, if the statement were true, it would imply that different cell types have distinct genetic material, which is not accurate for somatic cells in a multicellular organism. Stem cells, however, possess the ability to differentiate into various cell types, but they too contain the same DNA as other cells.
