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 nucleus is the command and control centre of the cell. It is essentially a minute computer which stores instructions in the form of DNA (deoxyribonucleic acid or deoxyribose nucleic acid).olypeptides are made of amino acids (see protein structure) and the number and order or sequence of the 20 different types of amino acid that make proteins must be coded for in the DNA so that the polypeptide contains the right amino acid in a given place.
