Description (Brief)
This silver metal canister once contained DNA-polymerase, an enzyme commonly used in molecular biology. In living organisms, it plays an important role in DNA replication and repair, by helping to speed along the process of linking together nucleotide bases into the chains that make up DNA.
This particular canister of DNA-polymerase was used in DNA sequencing efforts at the labs at Genentech, a biotechnology company, in the early 1980s.
