Winter Quarter Midterm Flashcards
genetic determinism
the idea that human qualities are genetically determined by genetic code alone
phenotype
physical characteristics
genotype
genetic code
epigenetics
the study of environmental influences on gene expression that occur with a DNA change
the promoter region
portion of DNA upstream from a gene, where transcription factors bind to enable RNA polymerase to start a transcription
epigenetic marks/tags
changes on how our cells interpret the information in our DNA
PBB (polybrominated Biphenyls)
a type of POP that is a flame suppressant
POP (persistant Organic Pollutant)
toxin resulting from a manufacturing process which remains in the environment for years
endocrine disruptore
chemicals that interfere with the normal functioning of hormones in the body
epidemiology
study of health patterns an their causes
DOHD (Developmental Origins of Health and Disease)
early life conditions shape development with health outcomes observed later in life
PTSD
complex interplay between genes and environment
hypothalamic-pituitary-adrenal (HPA) axis
a body system involved in stress responses
Forms of Transmission across Generations
utero, parental care, and chemical changes in the germline
Utero form of transmission
direct effect of trauma on maternal sress hormone (direct exposure)
parent care transmission
trauma affects parents’ care which influences the health and behavior of offspring in the absence of exposure
chemical changes in the germline transmission
trauma and other environmental exposure might permananetly alter the cell line production of gametes (eggs and sperm) for many generations through epigenetic marks (inheritance)
germline
line of cells that produce eggs and sperm
Histone modification (DNA Acetylation)
activates and enhances transcription
green revolution
agricultural revolution that increased production through improved seeds and fertilizers and practices
racial logic
creation and maintenance of racial order
malthusian
overpopulation is the root cause of poverty, illness, and warfare
molecularization/molecularized marketing
focusing on eating for key components or outcomes, food is seen only as something that shapes our bodies (yogurt commercials)
settler colonialism
immigrants seize land from indigenous population and become dominant population
biopiracy
theft of biological materials
bio-prospecting
discovery and patent of biological matter (generally in agriculture and seeds)
bio-colonialism
taking biological knowledge or resources for profit and without consent, especially from indigenous and marginalized communities
terra nullius
land that belongs to no one
Nutritional epigenetics
food type and availability during critical periods affect pattern of gene expression
