DNA is the most important molecule in living cells, containing the genetic codes for all organisms. It is found in extremely long strands within the human body, with over 9 million kilometers of DNA coiled inside each person. DNA also stores an immense amount of information efficiently, able to hold 10 gigabytes per centimeter and sharing around 50% of its content with bananas.

1. DNA is the
single most
important
molecule in
living cells

2. DNA are large
molecules –
You have about
9 MILLION
KILOMETRES of
DNA in your
body

3. If you were to
write down the
codes for all the
chemicals in
your DNA it
would fill about
200 phone
books –
about 3 billion
letters

4. Around 99.1%
of our genes or
instructions are
in common with
the
chimpanzee,
which is our
closest relative
on earth

5. About 50
percent of
human DNA is
the same as the
DNA found in
bananas

6. DNA can store
10 gigabytes of
information per
cm. It is the
most efficient
storage system
known to
humans

7. In the past,
people thought
that heredity
was passed on
through our
blood –
However, the
red blood cells
have no DNA !
