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.

The parts of the nucleus reflect its functions. Most of the time, the entire nucleus is separated from the rest of the cell by a double-layered nuclear envelope. This membrane is covered with pores that regulate the movement of molecules in and out of the nucleus. Inside the nucleus, the nucleolus produces ribosomes, which make proteins for the cell.
