A mutation is a change in the sequence of an organism's DNA. What causes a mutation? Mutations can be caused by high-energy sources such as radiation or by chemicals in the environment. They can also ...

As mutation affects essentially every aspect of biology, the development of a unifying theory for mutation-rate evolution is highly desirable. There is much to be explained. For although the ...

Translocations, in genetics, happen when chromosomes break and the pieces attach to other chromosomes. This mixing of genetic material has important results. The resultant chromosomes are lacking in ...

Most cancer researchers are convinced that cancer results from a handful of genetic mutations that kick a cell into uncontrolled growth. UC Berkeley genetics researcher Peter Duesberg disagrees, and ...

Variations in the properties of arabica coffee, such as in taste, caffeine content and disease resistance, are determined by chromosome mutations, according to a recent study. But are these findings ...

Genetic disorders can occur due to mutations in one gene (monogenic), multiple genes (multifactorial inheritance), and mutation in one or more chromosomes. Point mutations are where one nucleotide in ...
