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 is a series of waves or surges most commonly caused by an earthquake beneath the sea floor. Tsunamis can cause great loss of life and property damage in coastal areas.Very large tsunamis can cause damage to coastal regions thousands of miles away from the earthquake that caused them.1  Beaches, lagoons, bays, estuaries, tidal flats and river mouths are the most dangerous places to be.ery large tsunamis can cause damage to coastal regions thousands of miles away from the earthquake that caused them. 1  Beaches, lagoons, bays, estuaries, tidal flats and river mouths are the most dangerous places to be.
