DNA mediate the function of the genome. Genomic DNA is tightly and orderly packed in the process called DNA condensation, to fit the small available volumes of the cell. In eukaryotes, DNA is located in the cell nucleus, with small amounts in mitochondria and chloroplasts. In prokaryotes, the DNA is held within an irregularly shaped body in the cytoplasm called the nucleoid. The genetic information in a genome is held within genes, and the complete set of this information in an organism is called its genotype. A gene is a unit of heredity and is a region of DNA that influences
DNA laddering along with DNA laddering such as TEM and TUNEL. With recent improvements to DNA laddering, DNA laddering has become a more reliable, and reasonable technique to use when detecting apoptosis. It is also important to note that DNA laddering occurs differently depending on the type of cell, so there may be slight changes in the process of DNA laddering depending on the cell that is being investigated. DNA laddering DNA laddering is a feature that can be observed when DNA fragments, resulting from apoptotic DNA fragmentation, are visualized after separation by gel electrophoresis. It was first described in 1980 by
