The most-critical point of reproductive development in all sexually reproducing species is the transition from mitotic to meiotic cell cycle. Studies in unicellular fungi have indicated that the decision to enter meiosis must be made before the beginning of the premeiotic S phase. Recent data from the mouse suggest that this timing of meiosis initiation is a universal feature shared also by mul...

Meiosis Networks 533 A central problem in connectionist modelling is the control of network and architectural resources during learning. In the present approach, weights reflect a coarse prediction history as coded by a distribution of values and parameterized in the mean and standard deviation of these weight distributions. Weight updates are a function of both the mean and standard deviation ...

Background: Maternal mRNA degradation is a selective process that occurs in waves corresponding to important developmental transitions such as resumption of meiosis, fertilization and zygotic genome activation. It has been demonstrated that the number, position, and combination of 3 UTR cis-acting elements interacting with trans-acting protein factors regulate translation and mRNA stability. Ou...
