DNA, the nucleotide Adenine always bonds with
which one?
1. Cytosine

Note the antiparallel (facing
opposite directions)
strands joined by
complementary
nitrogenous base pairs
between the
deoxyribonucleotides:
A to T and C to G
Hydrogen bonds (H bonds) attract the
nitrogenous base pairs to each other
and hold the 2 strands of Dna together
in the double helix
The 2 halves of the DNA double helix are comprised of
H bonded complementary, but anti-parallel,
deoxyribonucleotide base pairs.

Each gene contains the pattern for a
particular protein (the order in which
to put amino acid monomers
together to build the polymer called
a protein.
Proteins are the tools that carry out
all the jobs and build most of the
structures in our cells.
