Introducing Epigenetics

  • Sofiahas quoted4 years ago
    RNA is similar to DNA, but its short, single strands are less stable and more mobile than the DNA’s long double helix.
  • Laura Luciahas quoted4 years ago
    “Epi-” means upon, or in addition; epigenetics is the study of how additional factors interact with genes to direct the processes that make our cells* and bodies work.
  • obiteljkosic01has quoted5 years ago
    nature (our genes) and nurture (our environment, experiences and other non-genetic factors)
  • obiteljkosic01has quoted5 years ago
    However, a few hundred imprinted genes are transcribed from only the maternally-inherited chromosome, and others from only the paternally-inherited chromosome.
  • obiteljkosic01has quoted5 years ago
    every cell in the human body contains exactly the same DNA as the original fertilized zygote.
  • obiteljkosic01has quoted5 years ago
    This experiment proved that fully differentiated cells retain all the genetic material needed to produce every cell in the body.
  • obiteljkosic01has quoted5 years ago
    DNA was characterized in 1953 by Watson, Crick, Wilkins and Franklin.
  • obiteljkosic01has quoted5 years ago
    exception, identical twins, come from a single fertilized zygote that splits in two.
  • obiteljkosic01has quoted5 years ago
    Each of the four new cells created during a single meiosis event therefore receives 23 chromosomes, rather than the 23 pairs of chromosomes found in most other cells.
  • obiteljkosic01has quoted5 years ago
    The combination of DNA, histones and scaffold proteins, plus other proteins and RNAs that bind to the overall structure, is called chromatin*.
