This type of mutation may alter the function of the resulting protein. This type of mutation occurs when the addition or loss of DNA bases changes a gene's reading frame. A reading frame consists of groups of 3 bases that each code for one amino acid.
Tsunami is a Japanese word with the English translation: harbour wave. In the past, tsunamis have been referred to as tidal waves or seismic sea waves. The term tidal wave is misleading; even though a tsunami's impact upon a coastline is dependent upon the tidal level at the time a tsunami strikes, tsunamis are unrelated to the tides. (Tides result from the gravitational influences of the moon, sun, and planets.) The term seismic sea wave is also misleading.
A tsunami (plural: tsunamis or tsunami; from Japanese: æ´¥æ³¢, lit. harbor wave; English pronunciation: /tsuËËnÉËmi/) , also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.he term tsunami, meaning harbor wave in literal translation, comes from the Japanese æ´¥æ³¢, composed of the two kanji æ´¥ (tsu) meaning  harbor  and æ³¢ (nami), meaning  wave . (For the plural, one can either follow ordinary English practice and add an s, or use an invariable plural as in the Japanese.
