ABSTRACT
Deoxyribonucleic acid (DNA) holds the codes for life. Because DNA is passed from one generation to the next, it is entirely possible that one could have some of the same exact DNA that an ancestor had hundreds of years ago. DNA is so small that it takes a powerful electron microscope to see it. One of the organelles, the nucleus, has the job of holding the DNA, called the control center or brain of the cell. The base on a DNA nucleotides is the foundation for the DNA language. Because the DNA is different in mitochondria, some scientists believe that they are once prokaryotes that swallowed by eukaryotes. The DNA is stationed inside the nucleus and has an assistant carry its messages out to the cell. During interphase, the nucleus contains many coils and loops of a material called chromatin. The assistant is called Ribonucleic acid (RNA). A nucleotide of RNA contains a ribose sugar.
