Beschreibung
Terminal Deoxynucleotidyl Transferase (TdT) is a template-independent DNA polymerase that catalyzes the repetitive addition of deoxynucleotides to the 3'-hydroxyl termini of oligonucleotides, single-stranded, and double-stranded DNA. The TdT reaction requires short sequences of at least three bases to act as primers. When using RNA as a substrate, TdT activity is highly dependent on the tertiary structure and nucleotide composition at the 3’-end of the acceptor RNA. In general, TdT exhibits lower efficiency with RNA templates compared to DNA templates.
