WebCultured human thyroid cells were X-irradiated in vitro and assayed for resistance to 6-thioguanine. The average mutant frequency was 1.69 +/- 1.34 X 10(-5) (mean +/- SD) in controls, 3.74 +/- 2.21 X 10(-5) in cells exposed to 1 Gy, and 7.19 +/- 5.37 X 10(-5) in cells exposed to 2 Gy. The positive association between mutant frequency and dose was … WebThis cell is in interphase (late G _2 2 phase) and has already copied its DNA, so the chromosomes in the nucleus each consist of two connected copies, called sister chromatids. You can’t see the chromosomes very clearly at this point, because they are still in their long, stringy, decondensed form.
