1 Copy number variation (CNV) is a type of mutation where large chunks of DNA are inserted, repeated or lost. 2  These regions of DNA can be between 10,000 and 5,000,000 bases long. 3  Duplication of genes. 4  When there is an increase in the number of copies of a gene. 5  Deletions of large regions of the chromosome.
Microwaves are basically small (micro) waves of radio frequency energy. It cooks the food by vibration (waves) creating friction from within, thus creating heat. This is why it cooks from the inside-out as opposed to heat which must be absorbed from the outside-in. Microwaves are high energy electromagnetic waves.
Microwave radiation can heat body tissue the same way it heats food. Exposure to high levels of microwaves can cause a painful burn. Two areas of the body, the eyes and the testes, are particularly vulnerable to RF heating because there is relatively little blood flow in them to carry away excess heat.
