PCT No. PCT/GB94/02630 Sec. 371 Date May 24, 1996 Sec. 102(e) Date May 24, 1996 PCT Filed Dec. 1, 1994 PCT Pub. No. WO95/15395 PCT Pub. Date Jun. 8, 1995A method is provided of making a dideoxynucleoside mono-or tri-phosphate, which is optionally 32-P or 33-P or 35-S radiolabelled which involves reacting the corresponding dideoxynucleoside with an optionally radiolabelled nucleotide phosphate or thiophosphate donor in the presence of a kinase of phosphotransferase enzyme which catalyses the reaction. A method of sequencing nucleic acids by a chain termination of a kinase or phosphotransferase enzyme which catalyses the reaction. A method of sequencing nucleic acids by a chain termination technique involves detecting the products of enzymatic synthesis by means of isotopically labelled chain terminating nucleotide analogues.
