Integrated retroviral DNA encodes three genes, called gag, env, and pol. All retrotransposons carry pol, and some contain gag, but none have env. How do retroviruses differ from retrotransposons?

Retrotransposons are unable to synthesize dsDNA from ssRNA.

Retrotransposons are able to synthesize dsDNA from ssRNA and can transpose the DNA throughout the genome, but they cannot produce protein particles.

Retrotransposons are able to synthesize dsDNA from ssRNA and can transpose the DNA throughout the genome, and they cannot produce protein intact retroviral particles when they are excised from the genome.

Retrotransposons are able to synthesize dsDNA from ssRNA, but cannot use the cut-and-paste method to transpose the DNA throughout the genome.
