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.
What is it? A tsunami, or seismic sea wave, is a series of destructive and very dangerous waves that result from earthquakes or other types of disturbances such as volcanic eruptions, meteorite impacts, and landslides. Its waves can get up to 30 m (100 ft) tall--or as high as a 10-story building.sunamis are extremely deadly and can't be predicted, so they are rarely caught on camera and you won't have much time to react when you spot the first wave coming in. They can wipe out an entire population of people and bring a city down to its knees.
