Viruses are not cells and cannot divide. They infect a host cell and use the host’s replication processes to produce identical progeny virus particles. Viruses infect organisms as diverse as bacteria, plants, and animals and exist in a netherworld between a living organism and a nonliving entity. Living things grow, metabolize, and reproduce.

One is an integrase, which is an endonuclease that cleaves at the site of integration to generate a staggered break. The other is RNA-dependent DNA polymerase, also called reverse transcriptase. These activities are encoded in some autonomous retrotransposons, including both LTR-retrotransposons and non-LTR-retrotransposons.

It highlights their structure, including an outer envelope and reverse transcriptase that converts RNA to DNA for integration into the host genome. The retroviral lifecycle involves reverse transcription and the production of new virions.
