The aforementioned Hershey-Chase experiment used the T2 type of these organisms, while other oft-studied types include T4 and lambda.
Some cells respond to the activity of these organisms by detecting PAM sites using Cas proteins in a pathway based on CRISPR ["crisper"] loci. These organisms bind proteins such as pN to RNA polymerase in the process of Q antitermination. An experiment involving these organisms labeled them with radioactive phosphorus and sulfur probes, which showed that DNA and not protein was the carrier of genetic information. The aforementioned Hershey-Chase experiment used the T2 type of these organisms, while other oft-studied types include T4 and lambda. For 10 points, name these viruses that attack bacteria.
