PSYC 110 Chapter Notes - Chapter 3: Mendelian Inheritance, Twin, Genetic Diversity
Document Summary
Modification as a result of changed life circumstances. Evolution long-term adaptive process, spanning generations, that equips each species for life in its ever-changing natural habitat. A class of proteins called structural proteins forms the structure of every cell of the body---creates who we are. Each protein molecule consists of a long chain of smaller molecules called amino acids. A single protein molecule may contain anywhere from several hundred up to many thousand amino acids in its chain. Some portions of the dna in cells serve as templates for producing another molecular substance called. Rna(ribonucleic acid), which in turn serves as a template for producing protein molecules. Genes work only thru interaction with the environment. One"s body and behavioral capacities result from a continuous, complex interplay btw. genes and environment. Genes are always expressed in a context. Researchers have begun to learn abt specific mechanisms thru which experiences can activate genes and thereby alter the individual"s brain and behavior.
