Reverse-transcribing viruses are classified into 5 different families, Retroviridae, Metaviridae, Pseudoviridae, Caulimoviridae, and Hepadnaviridae (1). Retroviruses, hepadnaviruses, and caulimoviruses are full-fledged viruses, whereas metaviruses and pseudoviruses are more often referred to as retrotransposons. Nevertheless [...]
