Our hands, our eyes , our face
our all body is an aggregate of billions of cells.
At the heart of each of them is nestled the DNA,
the one that we received from our parents
and that we'll transfer to our children.
What is exactly passed
from one generation to the other,
from one cell to the other?
We know that DNA is transmitted
but not only DNA.
Identical twins
have the same DNA,
the same genome,
and nonetheless have physical differences.
How is that possible?
The genome has been considered like a book
and indeed book's editions can be
very different from each other.
Scientist have assumed for a long time
that DNA ruled our biologic destiny.
Nowadays they're discovering a new world:
we're becoming more and more aware that
DNA doesn't explain everything.
And more and more capable of cultivating
the ideas about the impact of the environment.
All around the world,
biologists are investigating this new mystery.
My job is to look into
the cellular nucleus
for new knowledge
and to reach places that people have never reached before.
A scientific adventure
in which we seek to unravel step by step
what influences our DNA
during our intere lifetime,
our identity
and, possibly, our inheritance.
