Answer:
No
Step-by-step explanation:
All your cells in the body have same DNA. The difference comes from how we control the expression of different genes in those tissues. There's a reason you can't hear with your heart or your ears dont beat, its because the tissue in that region of body expresses some gene and blocks others. This creates the diversity in tissues we see in humans and entire living organism spectrum.
In conclusion, no every part of body has same DNA, the difference comes from how we control the signalling and expression of certain genes.
