The mammalian epigenome
Splet01. maj 2014 · The mammalian genome consists of approximately 3000 megabases of DNA packaged into chromatin within the cell nucleus. The basic subunits of chromatin are nucleosomes, which comprise the DNA double helix wrapped around octamers of histone proteins including H2A, H2B, H3, and H4, at 147 base pair intervals ( Kornberg and Lorch, … SpletMammalian reproduction requires union of two highly specialized cells, the egg and sperm, at fertilization, an event that marks the beginning of new life. Epigenetic marks of this newly formed genome are immediately required to establish the cell type–specific gene expression programs required for embryonic growth and development.
