2. Getting to Know
the DNA and
RNA structures

3. What is DNA?
Deoxyribonucleic acid (DNA)
is a molecule that contains
the biological instructions
that make each species
unique.
DNA, along with the
instructions it contains, is
passed from adult organisms
to their offspring during
reproduction.

4. What is DNA
made of? DNA is made of chemical building
blocks called nucleotides.
These building blocks are made of
three parts: a phosphate group, a
sugar group and one of four types
of nitrogen bases.
To form a strand of DNA,
nucleotides are linked into chains,
with the phosphate and sugar
groups alternating.
