Hydroxymethyl uracil replaces thymine in the genome of the SPO1 type of these, which also has a baseplate that is rearranged during tail contraction into a hexameric pinwheel.

Production of the most common protein in the MS2 variety is inhibited by dimers of its coat protein. Lederberg and Zinder demonstrated the transfer of genetic material via these by labeling parts of them with sulfur-35 and phosphorus-32 to help confirm that DNA was the genetic material of the Hershey-Chase experiment. The T4 variety only reproduces via the lytic cycle, while the lambda type may also use the lysogenic cycle. For 10 points, name these viruses that infect bacteria.
