PPT-Epigenetics

DNA methylation I Requirements for epigenetic materials Need to be transmitted faithfully during mitosis and meiosis possibly along with DNA gt cell need to have maintenance mechanisms similar to semiconservative mechanism of DNA replication. 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 Assisted Reproduction Technology.
