Differentiated cells of an organism contain the same genes. (among the few exceptions to this rule are the cells of the mammalian immune system, in which the formation of specialized cells is based on limited rearrangements of the genome.) describe an experiment that substantiates the first sentence of this question, and explain why it does.

A perfect experiment to substantiate the claim that all d ifferentiated cells of an organism contain the same genes would include the following steps.

1 Extraction of the DNA from different differentiated cells of the same organism

2 Sequencing the extracted DNA

3 comparing the DNA sequences

The DNA sequences we would observe would be identical, proving empirically that all of the cells in an organism contain the same DNA, and therefore the same genes.
