Figure 3. Effect of DNA synthesis inhibition on Tktl1 transcriptional activity in two-cell-stage embryos.

Transcription of pTktl1-2467+25 was measured in embryos in which DNA synthesis was inhibited by treatment with aphidicolin. Experiments were performed three times and the results are presented as means ± SEM. Asterisks indicate significant differences (Student's t-test; P<0.05).
