Copia transposition process. (a) Copia transcription. (b) copia mRNA processing and translation of gag, pol, int, and Rnase transcripts in the cytoplasm. (c) Translated proteins are delivered into the nucleus and VLPs are assembles from gag proteins. (d) Inside the VLPs, reverse transcription of full-length mRNA into DNA. (e) Complex strain exchanges required to fully replicate the two long terminal repeats (LTRs) to produce linear DNA, single and double LTR extrachromosomal plasmids. Finally, integration of a newborn element into the host genome occurs.
