Viruses reproduce by incorporating
their DNA into an organism's genome to tap into the
host replication mechanism to reproduce themselves.
Viruses, therefore, cannot copy outside their host. This property of viruses makes them suitable
for the production of transgenic
organisms. This is achieved by replacing
the DNA piece that causes virulence in the virus with the desired gene
that is to be transduced into the host organisms.
The principle of faunal succession<span>, also known as the law of </span>faunal succession<span>, is based on the observation that sedimentary rock strata contain fossilized flora and fauna, and that these fossils succeed each other vertically in a specific, reliable order that </span>can<span> be identified over wide horizontal distances.</span>
