See how genes and genetic engineering work. Build models of DNA, and work out how it is copied as cells divide. Discover how the codes carried in the genes are copied and used to build proteins. See how gene splicing can be used to benefit human lives. For example, model the transfer of a human gene into bacteria, so they produce insulin. This learning object is a combination of five objects in the same series. The objects progressively increase in difficulty.
