Transcript

  • 1. “Orphan Experiences Lead toChanges in Children’s Genome Function” Yale School of Medicine Chavi & Elana Biology 3 Santa Monica College
  • 2. Gene ExpressionThe process of taking information contained ingenes on the DNA and turning the information intoproteins through transcription and translation. Thisprocess is used by all known living things.
  • 3. Transcription & Translation DNA remains in the nucleus until it is expressedthrough the process of transcription and translation.
  • 4. Nature vs. Nurture(It’s actually secretly genetics vs. epigenetics) GAME: LICK YOUR PUP!
  • 5. Study Professors at Yale mapped the genomes of 28 children.Control Group: Experimental group:14 children raised by their 14 orphans raised in an biological families institution
  • 6. StudyPurpose:To identify which biological processes are effected by lack of parental care.Results:Differences in DNA methylation which effects how genes are expressed including a number of important mechanisms in the development and function of the brain.
  • 7. ConclusionSeparation from a biological parent impacts long-term programming of genome function.
  • 8. Relevance• Working with children/people• Understanding your own psychological baggage• Recognizing how intertwined environment and biology are• Hug your kids• More fodder for the nature vs. nurture debate
  • 9. CritiqueThe good The bad• Controlled for • Small sample size age and • Correlation not causation environment. • Difference might be due to being raised in an institution. An orphan in an adoptive home might not experience the same effects.
  • 10.

  • 11. We know your time is limited. There’s so much more to learn so just incase you’reinterested in epeginetics Chavi’s twitter is @chavarisa. Please do not repress your scientific imagination. she’s available at all hours to answer questions. All questions. (of course as they relate to epigenetics and methylazation.
