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.

Microtubules are shaped like soda straws and give the nucleus and cell its shape. The nucleus in the center of a cell is a spherical body containing the nucleolus that makes ribosomes. The nucleus controls many of the functions of the cell (by controlling protein synthesis). It also contains DNA assembled into chromosomes. The nucleus is surrounded by the nuclear membrane.
