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.
The Japanese word tsunami means big wave, and it's the preferred way to refer to the phenomena that used to be known as tidal waves. Tsunamis don't have much to do with ocean tides -- they are created by seismic events, such as earthquakes and landslides on the ocean floor.any tsunamis are too small to notice, but some can have a leading wave as tall as 30 meters or more. As powerful as a wave this size is, however, it's the mass of water behind it that is responsible for most of the physical destruction.
