The antiparallel structure of DNA is important in DNA replication because it replicates the leading strand one way and the lagging strand the other way. During DNA replication the leading strand is replicated continuously whereas the lagging strand is replicated in segments known as Okazaki fragments.
The DNA of an organism are packed in their cells to protected, they also regulate the accessibility of the DNA. Packaging of DNA helps conserve space in the cells. Approximately, two meters of the human DNA can fit into a cell that is only a few micrometers wide. Chromosomes are made up of DNA segments. Chromosomes carry all the information that help a cell grows, survive and reproduce. DNA segments with specific patterns are called genes. The chromosomes are found in the nucle us of the cell. In prokaryotic organisms, the DNA is not present in the nucleus; the DNA floats in the cytoplasm in area called the nucleoid. The chromosomes vary widely between different organisms.
