Exogenote

<p>An exogenote is a piece of donor <a href="/facts/DNA/nB89Iauz">DNA</a> that is involved in the mating of <a href="/facts/Prokaryotic_organism/oYyvaDDH">prokaryotic organisms</a>.
</p><p>Transferred DNA of Hfr (high frequency of recombination) is called exogenote and homologous part of F (fertility factor) genophore is called endogenote. An exogenote is genetic material that is released into the environment by prokaryotic cells, usually upon their <a href="/facts/Lysis/th8pXeEn">lysis</a>. This exogenous genetic material is then free to be taken up by other competent bacteria, and used as a template for protein synthesis or broken down for its molecules to be used elsewhere in the cell. Taking up genetic material into the cell from the surrounding environment is a form of <a href="/facts/Transformation_(genetics)/n82cCRCu">bacterial transformation</a>. Exogenotes can also be transferred directly from donor to recipient bacteria as an F'-plasmid in a process known as <a href="/facts/Bacterial_conjugation/WfeyKYC4">bacterial conjugation</a>. F'-plasmids only form if the F+ factor is incorrectly translated, and results in a small amount of donor DNA erroneously transferring to the recipient with very high efficiency.
