Table 2.

Cdt1 expression and Cdc2 phosphorylation are delayed upon UV irradiation

Event	Length of the delay (min)(*)	Average length of the delay (min)
Cdt1 expression	60, 50	55
Cdc2 phosphorylation	40, 50	45

(*) The levels of Cdt1 expression and Cdc2 phosphorylation were quantified and the length of the delay was measured at the point where Cdt1 expression and Cdc2 phosphorylation, respectively, reached 50% of its maximal value. Irradiations were carried out 3.5 hours after inoculation in medium.
