Deoxythymidine triphosphate (dTTP) is one of the four nucleoside triphosphates that are used in the in vivo synthesis of DNA. Unlike the other deoxyribonucleotide triphosphates, thymidine triphosphate does not contain the "deoxy" prefix in its name.[1] The corresponding ribonucleoside triphosphate is called 5-methyluridine triphosphate.

It can be used by DNA ligase to create overlapping "sticky ends" so that protruding ends of opened microbial plasmids may be closed up.
