Video 15: Thomas Sakmar, clip 3
Thomas Sakmar is a professor at Rockefeller University. His lab works on the role of several proteins involved in photochemistry, specifically how protein structure is related to function. Dr. Sakmar has a personal interest in the work done by Phoebus Levene.

Comments on some of the prevailing theories of the time and Phoebus Levene's basic hypothesis
Phoebus Levene's contributions -- the distinction between DNA and RNA.
Did Levene's tetranucleotide theory affect the development of ideas in the field of nucleic acid research?

Phoebus Levene, circa 1930.
Erwin Chargaff talks about his name for Chargaff's ratios.
Phoebus Aaron Theodor Levene, 1915.
Erwin Chargaff talks about his discovery â a major step for building the DNA model.
Erwin Chargaff was the first to accurately measure nucleotide amounts in DNA.
Erwin Chargaff found that in DNA, the ratios of adenine (A) to thymine (T) and guanine (G) to cytosine (C) are equal. This parity is obvious in the final DNA structure.
