As the diverse and intricate mechanisms of evolution have come to be understood, it has grown increasingly certain that the raw materials upon which they depend are the mutations of genes.

The field of evolution examines how organisms adapt to their environments over generations, but what about the evolution of ...

Thus, all mutations that affect the fitness of future generations are agents of evolution. Mutations are essential to evolution. Every genetic feature in every organism was, initially, the result ...

Thermo-sensitive genic male sterility 5 (tms5) is a widely used thermo-sensitive genic male sterile (TGMS) line for two-line ...

DNA contains genes that carry instructions for the manufacture of a protein. If a mutation occurs in a gene that results in a change to the sequence of DNA bases, then the structure of the protein ...

Charles Darwin's theory of evolution generated scientific debate ... Still others proposed that spontaneous, random mutations, or changes, in organisms accounted for the variety of species.

This paper addresses the important question of quantifying epistasis patterns, which affect the predictability of evolution, by reanalyzing a recently published combinatorial deep mutational scan ...

However, it rarely occurs in other cancer types, thus highlighting the need for large-scale analysis of rare cancers to identify the distinct mutations that underpin their evolution.

Antibiotics are powerful, fast-acting medications designed to eradicate bacterial infections. However, in recent years, their ...

Variation is the differences in the characteristics of organisms. It can be caused by the genes an individual inherits or the environment it lives in. Extensive genetic variation is contained ...

"The Chinese poultry lineage may have experienced more vaccine-driven selection compared to other lineages," the researchers ...
