What is DNA sequencing
... Both the Maxam-Gilbert and Sanger-Coulson methods can only produce about 400 bases of sequence at a time. Most genes are larger than this. To sequence a large DNA molecule it is cut up (using two or more different restriction enzymes) into different fragments and each fragment is sequenced in turn 1 ...

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.
