Document Summary
Sds 150 - lecture 2 - theories of development. Both genetic and epigenetic factors = interact with environmental variables to shape level of health and well being across lifespan. Chromosomes: strings of genetic material in the nuclei of cells, we have 23 pairs of them. Deoxyribonucleic acid (dna): chemical material that makes up chromosomes and genes. Genome: all the dna that an organism possess. Phenotype: an ind"s whole set of observable characteristics. Multifactorial inheritance = pattern of inheritance affected by both genes and the environment, ex; height. Mitochondrial inheritance: pattern of inheritance where cell"s mitochondrial dna is inherited from mother"s egg and not father"s sperm, ex; several disorders. Epigenetics: study of the gene regulation patterns that alter gene function. Epigenome: sum total of inherited and acquired molecular modifications to the genome, leads to changes in gene regulation w/o changing dna sequence. Epigenetic factors: inheritable and acquired gene regulation patterns that alter gene function.
