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.

Bound ribosomes also produce polypeptide hormones. A few proteins produced by bound ribosomes are used in the cell membrane and on the outer surface of the cell. Surface receptors and cell signaling proteins are produced by bound ribosomes.ree ribosomes produce proteins that are used by the cell. This includes proteins that are used for the metabolism of food. The free ribosomes produce enzymes involved in the metabolism of glucose. Bound ribosomes produce proteins that are transported out of the cell.
