... Human mtDNA does NOT have introns. Introns are non-coding SEQUENCES of the double helix. The absence of INTRONS in human mtDNA means that mutations will have a greater impact because all of the information is needed for normal cell structure and function; there is no “fluff” What does human mtDNA co ...

Cancer epigenetics
Cancer epigenetics is the study of epigenetic modifications to the genome of cancer cells that do not involve a change in the nucleotide sequence. Epigenetic alterations are as important as genetic mutations in a cell’s transformation to cancer, and their manipulation holds great promise for cancer prevention, detection, and therapy. In different types of cancer, a variety of epigenetic mechanisms can be perturbed, such as silencing of tumor suppressor genes and activation of oncogenes by altered CpG island methylation patterns, histone modifications, and dysregulation of DNA binding proteins. Several medications which have epigenetic impact are now used in several of these diseases.
