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 cell membrane is composed of lipids (phospholipids) and proteins. p. 20 (A, P) Nucleusâ control center for all cell functions. Within the nucleus are chromosomes and at least one nucleolus. The nucleolus is a site of RNA synthesis, and it may also be responsible for the production of ribosomes.
