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 ovens use high power electromagnetic radiation (radio) at a frequency. close to 2.5 GHz to do the job of cooking. Much of the design of the appliance goes into making sure that very little of that. radiation is given off, and that it stays inside the cooking chamber where it belongs.icrowave radiation is electromagnetic radiation (waves) in the microwave portion of the electromagnetic spectrum. (An electromagnetic wave is a moving electrostatic and magne â¦ tic field. The fields are at right angles to each other, and they move through space in just this way-as moving fields.
