Purpose
Adds dT at the end of PCR blunted DNA fragments/vectors that can then be used in TOPO cloning; Addition of homopolymer tails to the 3' ends of DNA; Labeling the 3' ends of DNA with modified nucleotides (e.g., ddNTP, DIG-dUTP); TUNEL assay (in situ localization of apoptosis); TdT dependent PCR
