Fig. 6. Plot showing the values of PCNA-I (squares) and PCNA-OD (circles) related
to the quantity of food eaten (diet 7:7, open bars; diet 21:21, solid bars)
through the first 8 days of the fifth instar for both diet 7:7 (lines) and
diet 21:21 (dotted lines). Both PCNA-I and PCNA-OD values increased between
day 0 and day 3 and decreased thereafter. Notice the correlation between the
amount of food eaten and the levels of both PCNA-I and PCNA-OD.
