Mitochondrial DNA Mitochondrial DNA Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. In humans, the 16,569 base pairs of mitochondrial DNA encode for only 37 genes. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. In
Crosslinking of DNA engineered using DNA cross-linking agents to interact with nitrogenous bases of DNA to block DNA replication. These cross-linking agents have the ability to act as single-agent therapies by targeting and destroying specific nucleotides in cancerous cells. This result is stopping the cycle and growth of cancer cells; because it inhibits specific DNA repair pathways, this approach has a potential advantage in having fewer side effects. In humans, the leading cause of cancer deaths worldwide is lung cancer, including non small cell lung carcinoma (NSCLC) which accounts for 85% of all lung cancer cases in the United States. Individuals with NSCLC
