RNTP
A ribonucleoside tri-phosphate is a ribonucleoside with 3 phosphate groups. rNTPs are the building blocks of RNA synthesis as well as the synthesis of primers in DNA replication. They also serve as stores of chemical energy, chiefly Adenosine triphosphate.
RNTP are also used during DNA replication for the creation of the 3'-OH.
