We report here investigations on the isochore pattern and the distribution of genes in the chromosomes of chicken. In spite of large differences in genome size and karyotype, the compositional properties and the gene distribution of the chicken genome are very similar to those recently published for the human genome, which is a good representative of most mammalian genomes. In fact, this similarity, which extends to the relative amounts and, also, to a large extent at least, to the average base composition of isochore families, is most interesting in view of the very large distance of mammals and birds for a common ancestor, which goes back to 310-340 million years ago. This raises important questions about genome evolution in vertebrates.
A new type of instability - electrokinetic instability - and an unusual
transition to chaotic motion near a charge-selective surface was studied by
numerical integration of the Nernst-Planck-Poisson-Stokes system and a weakly
nonlinear analysis near the threshold of instability. Two kinds of initia...
We present here compelling empirical evidence of a high level of
Regularity regarding time and spatial correlations in urban sprawl, unraveling
Patterns about the inertia in the growth of cities and their interaction with
Each other. By using one of the world's most exhaustive extant demographic dat...
We formulate a mathematical model to investigate the
Dynamic properties of histone modification patterns. We then illustrate that
Our modeling framework can be used to capture key features of experimentally
Observed combinatorial chromatin states....
