This is the name Fredrich Miescher gave to isolated DNA.
Nuclein
Albrecht Kossel
Who discovered hydrogen bonding?
James Creeth
Which two people are credited with the discovery of the double helix structure of DNA?
James Watson & Francis Crick
Miescher gathered DNA from these two sources.
Salmon sperm and pus from surgical bandages
Levene, while Russian at birth, emigrated to this country at the age of 22.
US of A
This school, which later was the place where DNA structure was modeled, rejected Creeth.
Cambridge
Who actually discovered the double helix structure in DNA?
Rosalind Franklin & Maurice Wilkins
Miescher died from what?
Tuberculosis
(from leaving the windows of his castle/lab open)
Through Levene's research, we learned the backbone of DNA. What were the components that he discovered?
Phosphoric acid, carbohydrate, and a base
What two things were missing from James Creeth's model for DNA?
Double Helix and breaks in the chains
What method was used to obtain images of DNA structure?
X-ray crystallography
Who discovered nucleic acids within nuclein?
Friedrich Miescher
Along with Stuart Tipson, Levene discovered this sugary portion of DNA
Deoxyribose sugar
What method was used in the discovery of hydrogen bonding?
Viscometry
Who discovered the 1:1 ratio of complimentary base pairs in DNA?
Erwin Chargaff
Who discovered the five nitrogen bases?
Albrecht Kossel
Levene was summoned to aid this dog-abusing psychologist.
Pavlov
What is Viscometry?
A technique used for determining viscosity
In reference to Watson and Crick, who said, "They had enormous ambition and aggressiveness, coupled with an almost complete ignorance of, and a contempt for, chemistry."
Erwin Chargaff
