Partial trisomy of the long arm of human chromosome 1 as demonstrated by in situ hybridization with 5S ribosomal RNA (1977)

Meilinger, Karen L., Kelch, Robert P., Wall, Patrick M., Speert, David P., Chu, Ernest H. Y., Steffensen, Dale M.

In a newborn boy with multiple malformations, a tandem duplication was detected at the distal end of the long arm of one human chromosome 1. The Giemsa bands, 1q31 to 1q43–44, were repeated...

INCORPORATION OF H3-THYMIDINE INTO CHLOROPLAST DNA OF MARINE ALGAE

Steffensen, Dale M., Sheridan, William F.

The chloroplasts of three genera of marine algae, Dictyota, Padina, and Bryopsis, were labeled with tritiated-thymidine for various time periods during culture in "Erd-Schreiber's" solution....
