Peptides on the surfaces of these entities can be used as a mirror image display to determine the D-peptides that will bind in the body to an L-protein.

Peptides on the surfaces of these entities can be used as a mirror image display to determine the D-peptides that will bind in the body to an L-protein. Streisinger developed his model of mutation using the lysozyme gene from one of these. One type of these entities has an experimentally useful rII (r two) mutant. Their morphology includes base plates and tail fibers. The Luria-Delbruck experiment showed these do not induce mutations that are harmful to their niche. The Hershey-Chase experiment also used one class of these raised on radioactive material to determine that DNA contained genetic information. Common examples of these entities include the lambda and T4 variants. For 10 points, name this type of virus that infects bacteria.
