I'm trying to make sense of some fundamental genetics and I struggle
with this
question;
If the only information in the dna that is relevant are genes (correct
me if I'm wrong)
it shouldnt matter if 2 genes changed position? Or does it?
If it does make a difference:
could conceivably 2 genes have the exact same nukleotid-sequence?

The reason I ask is to understand the "placement" of proteins.
If a protein from a specific gene is placed in som gland,how does it
know where
to go. If the answer is that only cells in that gland "use" that
specific
gene ,how does cells in other parts of the body know NOT to make that
protein.

As you see I'm new to this, references would be much appreciated!
