during the anaerobic period and for about 1 h following reoxygenation the dna synthesis of the cells was studied by determining the dna synthesis rate from [ 3h ] thymidine incorporation data , by evaluation of the thymidine ( pulse labelling ) index , by dna fibre autoradiography , and by alkaline sucrose gradients in order to follow the maturation of the daughter chains .
