Document Summary
Biological, bioecological and sociocultural theories: the adolescent brain. Dna: a molecule in the shape of a double helix that contains genetic information. Chromosome: made up of dna, a threadlike structure that is located in the nucleus. Genes: sequences of dna nucleotides that hold genetic information, often referred to as units of hereditary information. Genes are the sol cause of trait differences (ex: tall, thin, short, etc) Genotype: genetic material that we inherit that we cannot see or observe. Phenotype: observable ways that our genotype is expressed (ex: our height, colours of our eyes, etc) Genomics: study of an organisms entire genome aka all of its genetic information. Our body is not neatly sorted out, but is a complex web of interaction between our genes. Epigenetic: sub eld of genetics that aims to study these complex webs of interaction or how environmental factors in uence how our genes get expressed.
