Environment: every non-genetic influence, from prenatal nutrition to the people and things around us. Chromosomes: threadlike structures made of dna molecules that contain the genes. Dna (deoxyribonucleic acid): a complex molecule containing the genetic information that makes up the chromosomes. Genes: the biochemical units of heredity that made up the chromosomes segments of dna capable of synthesizing a protein. Genome: the complete instruction for making an organism, consisting of all the genetic material in that orga(cid:374)is(cid:373)"s (cid:272)hro(cid:373)oso(cid:373)es. Identical twin: twins who develop from a single fertilized egg that splits in two, creating two genetically identical organisms. Fraternal twins: twins who develop from separate fertilized eggs. They are genetically no closer than brother and sisters, but they share a fetal environment.
