{Reference Type}: Journal Article {Title}: Adenosine deaminases that act on RNA, then and now. {Author}: Bass BL; {Journal}: RNA {Volume}: 30 {Issue}: 5 {Year}: 2024 Apr 16 {Factor}: 5.636 {DOI}: 10.1261/rna.079990.124 {Abstract}: In this article, I recount my memories of key experiments that led to my entry into the RNA editing/modification field. I highlight initial observations made by the pioneers in the ADAR field, and how they fit into our current understanding of this family of enzymes. I discuss early mysteries that have now been solved, as well as those that still linger. Finally, I discuss important, outstanding questions and acknowledge my hope for the future of the RNA editing/modification field.
