Students come to understand that in sexually reproducing organisms, such as humans, typically half of the genes come from each parent. Students examine a fictional pedigree and determine which gene is responsible for a given trait. The genetic information for individuals is depicted as a jigsaw puzzle. Terms that students encounter include gene; chromosome; DNA; pedigree; genotype; phenotype; dominant; and recessive. Full Review »

Students simulate gene splicing by examining bacteria. They create a bacterial DNA into which they insert the human DNA (gene) that codes for growth hormone. They cut the sites of the enzyme to study how the human DNA can be joined to that of the bacterial plasmid to create recombinant DNA. Full Review »
