The resulting iteration between diversification and selection allows true Darwinian protein evolution to occur in vitro.
It suggests that cancer evolves by a process of clonal expansion, diversification, and selection within the tissue ecosystems.
Narrow diversification, the selection of exceptional stocks and sectors, can be your guiding light through these tough times.
These types of vehicles offer the benefits of diversification, professional selection and management, liquidity and ease of use.
Directed evolution is the experimental improvement of biocatalysts or cellular properties through iterative genetic diversification and selection procedures.
Recently, viral vector engineering involving high-throughput random diversification and selection has enabled the rapid creation of AAV vectors with valuable new gene delivery properties.
Ohno (1970), in particular, considered duplication and divergence of genes a critical requirement for major evolutionary diversification: "Natural selection merely modified while redundancy created," he wrote.
The ontogeny of lymphocytes in the bone marrow and thymus is resolved to fine detail, and it is clear that the molecular events regulating receptor diversification and selection according to the likelihood of self-reactivity are coregulated.
Eventually, a balance between mutation and recombination, which enhance viral diversification, and selection and drift, which constrain viral diversification, is reached; accordingly, dG, dS, and f attain equilibrium values.
During DE, parameter vectors are propagated from generation to generation by processes of diversification and selection.
