Figure 2. The period of high
fog-3 expression coincides with spermatogenesis. (A) Northern blot of N2 total RNA, isolated from different developmental stages. L1, first larval stage; yA, young adult; A, adult. The blot was probed with an anti-
fog-3 probe (Chen et al., 2000) and then with a probe to the 26s ribosomal RNA, to test for loading errors. (B) Northern blot of
him-5(
e1490) total RNA, processed as described in A. These populations contain 30% males and 70% hermaphrodites (Hodgkin et al., 1979).
