A Dynamic Stochastic Model for DNA Replication Initiation in Early Embryos

A Dynamic Stochastic Model for DNA Replication Initiation in Early Embryos

BACKGROUND Eukaryotic cells seem unable to monitor replication completion during normal S phase, yet must ensure a reliable replication completion time. This is an acute problem in early Xenopus embryos since DNA replication origins are located and activated stochastically, leading to the random completion problem. DNA combing, kinetic modelling and other studies using Xenopus egg extracts have...

Stochastic models for DNA replication

A statistician or probabilist entering into the biological domain may do so at a variety of levels. Most statisticians, when consulted for help by biologists, nd themselves dealing at the animal or plant level { the animal (or plant) is the experimental unit. Since measurements usually display considerable variability from animal to animal, the consulting statistician nds ready application for ...

Dynamic Labor Market in a Dynamic Stochastic General Equilibrium Model: Case Study of Iranian Economy

The labor market, as one of the four markets, plays an important role in economic growth and development. So review developments in the labor market because of its close relationship with developments in other sectors is of great importance. This study tries to examine the dynamics of the labor market by adjusting for a New Keynesian dynamic stochastic general equilibrium model for the Iranian ...

X-chromosome replication in early rabbit embryos.

is generally believed that the sex chromatin which is found in the cells of 'Lammalian Eemales represents a genetically inactive X chromosome (LYON 1961 ; RUSSELL 1961 ) iwhich is heterochromatic and is replicated out of synchrony with the other X (ATKINS, TAFT and DALAL 1962; GRUMBACH, MORISHIMA and TAYLOR 1963; OHNO and CATTANACH 1962). According to the single-active-X hypothesis, inactivatio...
