In 2000, the artist Eduardo Kac unveiled his bio-engineered art piece named “Alba,” a transgenic rabbit created using transformation. Alba’s cells carried a gene derived from jellyfish that produces GFP, a green fluorescent protein. When Alba was illuminated with UV light, she fluoresced a bright lime green color. To create Alba, genetic engineers had to first create a/an recombinant DNA vector that consisted of a jellyfish [coding] gene that produced GFP and a rabbit [regulatory] gene. This vector was then inserted into the genome of the embryo that ultimately developed into Alba.

To make copies of specific DNA sequences in the lab, scientists use polymerase chain reaction (PCR). During PCR, heat is used to “unzip” the two strands that comprise the DNA molecule. PCR mimics DNA replication in some ways, but not in how the two strands are pulled apart. How are the two strands of DNA unzipped during DNA replication in the cell?
