Is it possible to have "too many" mutations? What about "too few"? While mutations are necessary for evolution, they can damage existing adaptations as well. The statement that mutations are ...

How could a "bad" gene-- the mutation that causes the sometimes lethal sickle cell disease -- also be beneficial? On the other hand, if it didn't provide some survival advantage, why had the ...

A frameshift mutation is a genetic mutation caused by a deletion or insertion in a DNA sequence that shifts the way the sequence is read. A DNA sequence is a chain of many smaller molecules called ...

Mutations occur continuously and can be spontaneous. Most are caused by errors when the DNA is copied prior to cell division. They can also happen because of: ionising radiation close ionising ...

Applied since the 1930s to accelerate the process of developing and selecting new valuable agronomic traits, mutation breeding uses a plant’s own genetic make-up, mimicking the natural process of ...

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 ...

A genetic mutation found in two human patients with schizophrenia also increased schizophrenia-related behaviors in mice with the same mutation, a rare finding of a direct genetic link to psychosis, ...

The study of Ecuadorian families with a rare disease known as Laron Syndrome has just shown that a genetic mutation protects ...

The next step in mutation breeding is to detect which plants have indeed produced the desired new traits. With recent breakthroughs in detection technologies we help Member States screen plants more ...
