Retroviruses are a sub-category of oncoviruses that include the lentiviruses. Retroviruses are negative single-stranded RNA viruses in which tRNA serves as a primer for the mRNA synthesis. The mRNA is ...

For retroviruses in general ... In a poorly understood process referred to as ‘uncoating’, the core undergoes re-organization to form a reverse transcription complex (RTC).

The researchers discovered that the synthesis of myelin in fish, amphibians, and mammals depends on a genetic element called a “retrotransposon,” which is derived from a retrovirus.

"Retroviruses were required for vertebrate ... which suggests that RetroMyelin was acquired multiple times through the ...
