BAC to the future: functional genomics in mammals

Assen Roguev & Nevan J Krogan

DNA engineering technology, allowing one to assemble DNA fragments like Lego pieces, has revolutionized biology. In this issue, Poser, Sarov and colleagues describe the BAC TransgeneOmics pipeline—a generic, high-throughput methodology that allows for the rapid generation of large DNA constructs, which will facilitate systematic characterization of protein function in mammals.
