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 ...
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.
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 ...
Researchers discovered that mammals - from tigers to humans - have roughly the same number of mutations by the time they die of old age. But short-lived animals tend to burn through their ...
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 ...
Sprue pickers are industrial robots that are designed to remove sprue from molded parts. The term “sprue” refers to the passage through which liquid or molten material is introduced, and to the excess ...
Sprue bushings are hardened-steel mold components that accept an extrusion nozzle and provide the opening used to transfer molten plastic to the mold cavity. They help reduce cooling times and produce ...

Irradiation can be used to induce mutations in plants with the goal to produce varieties that display improved product quality, have higher yields and yield stability, greater resilience to climate ...
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 ...
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 ...
Expert Rev Gastroenterol Hepatol. 2012;6(1):43-55. Improving Gluten Strength Gluten is important to the baking industry because it provides elasticity and shape to dough by forming a network of ...
