[3] The University of Oregon's Institute of Molecular Biology named their main building "Streisinger Hall" in his honor.

Streisinger was well known as an innovative professor in and out of the classroom, conscripting a dance class to illustrate protein synthesis, and often requested beginning and non-major biology students.

He was very politically active, organizing grass-roots resistance to the Vietnam war and legislative opposition to John Kennedy's civil defense program.

He testified to successfully ban mutagenic herbicides in Douglas fir reforestation, and led and won a battle to exclude secret war department research from the University of Oregon campus.

During his postdoc at Caltech, with Jean Weigle, he undertook further studies on T2 × T4 hybrids, which led to the discovery of DNA modification (by glucosylation).
