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.

RNA is moved out of the nucleus through the nuclear pores. Proteins needed inside the nucleus are transported in through the nuclear pores. The nucleolus is usually visible as a dark spot in the nucleus, and is the location of ribosome formation. Ribosomes are where RNA is translated into protein. This process is called protein synthesis. Protein synthesis is very important to cells, therefore large numbers of ribosomes are found in cells. Ribosomes float freely in the cytoplasm, and are also bound to the endoplasmic reticulum (ER). ER bound to ribosomes is called rough ER because the ribosomes on the ER give it a rough sandpaper like look.. These organelles are very small, made up of 50 proteins and several long RNAs bound together. Ribosomes do not have a membrane. Ribosomes fall into two seperate units while not synthesizing protein.
