DNA/Replication
As you might have noticed you
are a mixture of your biological parents and
preceding generations. Maybe you've got your mothers
nose and your fathers eyes. How can that be?
Something must carry that information between the
generations.
DNA is the physical carrier of inheritance. It is
like a giant book of information containing all the
instructions for building and maintaining a living
organism.
Replication followed by cell division is the answer
to one of life's most interesting questions: How can
the union of a single sperm and an egg become a
five-trillion-cell baby, all containing the same
DNA?
