### Terminal desoxynucleotidyl transferase (TdT) activity
+Like other DNA polymerases ([[Clark, 1988|biblio/2460825]]), reverse
+transcriptases have a TdT activity.
+
- [[Chen & Patton, 2001|biblio/11252793]] reported a TdT activity for MMLV and
AMV, with a preference for adding As. For MMLV, activity reduced abruptly
between 45 and 50 °C. For AMV, it decreased constantly from 25 to 50 °C.
