Nels joins Vincent in New York City to speak with Stephen Goff about transmissible clam cancers and the silencing of integrated retroviral genomes.
Nels and Vincent reveal how introns – the parts of pre-mRNAs that are removed by splicing – were generated by DNA transposons in two different picoeukaryotes.
