Given the task definition and input, reply with output. In this task, you're given a paragraph from the research paper and your task is to generate a suitable title for the research paper based on the given paper. Under 100 words is a good title length.

The explosive pace of sequencing of RNA viruses is leading to rapid advances in our understanding of the evolution of these viruses and of the ways in which their genomes are organized and expressed. New insights are coming not only from genomic nucleotide sequence comparisons, but also from direct sequencing of transcribed mRNAs and of RNAs that serve as intermediates in replication. BSMV--barley stripe mosaic virus; L--large; Ldr~leader RNA; M~medium; NDV--Newcastle disease virus; NTR--non-translated region; ORF~open reading frame; PIV--parainfluenza virus; S~small; ssRNA--single-strand RNA; SVS~simian virus 5; TMV--tobacco mosaic virus; vc RNA--virus complementary RNA.
