Once generated, a tsunami wave in the open ocean can travel with speeds greater than 800 kilometres an hour (500 miles an hour). These waves can travel across the Pacific Ocean in less than one day. Locally generated tsunamis can reach coastlines in just minutes.
Although the nuclear DNA contains all of the information or codes necessary to make proteins, protein synthesis does not occur in the nucleus. Instead, an enzyme called RNA polymerase attaches to one end of a specific length of DNA and moves along the molecule making an RNA copy.lthough the nuclear DNA contains all of the information or codes necessary to make proteins, protein synthesis does not occur in the nucleus.

Proteins of the mammalian cell are synthesized on ribosomes that are either free in the cytosol or attached to the endoplasmic reticulum. Ribosomes suspended in the cytosol make proteins that function in the cytosol. Bound ribosomes make proteins that are included in the cell's membrane or exported from the cell.
