  • Title: [DNA reduplication cycle during chromosome polytenization in the salivary gland cells of Chironomus thummi larvae. III. The determination of the duration of the DNA synthesis period].
    Author: Gundrina LI, Sherudilo AI, Mitina RL.
    Journal: Tsitologiia; 1984 Aug; 26(8):927-35. PubMed ID: 6495395.
    Abstract:
    The duration of DNA synthesis in the salivary gland cells of Chironomus thummi larvae of the IV instar was determined by means of autoradiography and cytophotometry. Cells of different levels of ploidy differ in the duration of their DNA synthesis period. The tS of 2(10)c and 2(11)c cells was equal to 17 and 22 hours, respectively. The doubling of DNA content of the chironomid salivary gland cells leads to a 1.3 time increase in the duration of S-phase.
