Prokaryotic versions of this enzyme contain an OB 
Prokaryotic versions of this enzyme contain an OB fold and an adenylation domain. In Saccharomyces cerevisiae, this enzyme is encoded by the cdc9 gene. One form of this enzyme works with XRCC1 in the final step of short BER. Unlike other next generation sequencing technologies, SOLiD uses this enzyme to identify base pairs. The T4 version of this enzyme requires NAD+ to work and is commonly used in molecular biology. This enzyme takes a five prime phosphate and a three prime hydroxyl and creates a phosphodiester bond between them. This enzyme is used to combine Okazaki fragments. For 10 points, name this enzyme that links DNA fragments together.
