PPT-Epigenetics Joomyeong ‘

Joo Kim Louisiana State University What is Epigenetics the study of mitotically andor meiotically heritable changes in gene function that can not be explained by changes in DNA sequences Riggs et al 1996. When packed in a metaphase chromosome the DNA is compacted 5000 to 10000 fold Most if not all of the DNA is present in chromatin which is a complex of DNA with an equal weight of basic proteins called histones Histones are small proteins which are b expand, and possibly revolutionize, current understandings and practices of Focusing.TARTINGWITPARTICULARDEFINITIONOFOCUSING yet clear in the mind.
