Densities

... organises the genome , and another thing, remember also that each genome organisation is species specific. If a graph is drawn of the relative densities of GC we would get an undulating line of hills and valleys, with the gene distribution being mainly around the hill sections of the genome ...

... (at which point they grew about 70% faster than the ancestor strain). All populations evolved larger cell volumes and lower maximum population densities, and all became specialized for living on glucose (with declines in fitness relative to the ancestor strain when grown in dissimilar nutrients). ...

... were almost exact copies of each other. The other observation he noted was that the same patterns exist in the equivalent Alu (which are SINES) densities of the human genome. This pattern also exists in other mammalian genomes. That is why he refers to the patterns as being remarkable. Now it ...

Both these elements are types of mobile DNA ...

... mentions other examples of evolution in the introduction, including: higher growth rates on glucose, shorter lag phases, reduced peak population densities, larger average size, increased DNA supercoiling, defects in DNA repair, and changes in many gene-expression profiles. In fact, there are ...
