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.

Ribosomes are organelles that synthesize proteins for the cell and send protein to the nucleus. Ribosomes can be free floating in the cytoplasm, or can be attached to the outer surfaces of the rough endoplasmic reticulum and are known as bound ribosomes.ibosomes are either floating in the cytoplasm or attached to membranes. In general, free-floating ribosomes produce proteins that are used inside the cell, and membrane-attached ribosomes manufacture proteins for use outside the cell.
