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 genetic code<span> is called a </span>universal code<span> because all known organisms use the same four nucleotide bases; organism differ according to the arrangement of the nucleotide bases. The four nucleotide bases are adenine , thymine, cytosine and guanine. Three bases form an amino acid, also known as a codon</span>
