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 nucleolus directs the assembly of proteins within the cell nucleus. The nucleolus is the part of the nucleus containing most of the genes that code for the synthesis of ribosomal RNA (rRNA: the RNA molecules found in ribosomes).So rRNA is synthesized within the nucleolus.hile still within the nucleolus, these rRNA molecules are assembled, together with many protein molecules. into two subunits of future ribosomes. The subunits leave the nucleus through pores in the nuclear membrane, and enter the cytoplasm.
