.188 E Ring Phosphate .177 It has a hex washer188 E Ring Phosphate is a nucleotide analog that is used in molecular biology research. It is a structural analog of deoxyadenosine triphosphate (dATP), but with a phosphate group attached to the 5' carbon of the ribose ring instead of the 3' carbon. This modification makes 188 E Ring Phosphate a poor substrate for DNA polymerases, but it can be incorporated into DNA by terminal transferase. 188 E Ring Phosphate is often used in DNA sequencing
