Who built models to determine that DNA was a double helix shape with base pairs A-T and G-C in rungs between the sugar/phosphate backbone of DNA?

Back

Watson & Crick

Front

Worked on DNA imaging techniques and published Franklin's x-ray crystallography image of DNA

Back

Wilkins

Front

Who provided clear x-ray crystallography images of DNA?

Back

Franklin

Front

One of the first scientists to use x-ray crystallography to observe DNA, hypothesized that there was a helix shape. Options: Watson & Crick, Franklin, Wilkins, Pauling, Chargaff.

Back

Pauling

Front

Who discovered that there was the same amount of A and T in a cell, and C and G in a cell?

Back

Chargaff

Front

Using x-ray diffraction to determine the structure of a crystal, such as DNA

Back

x-ray crystallography

Front

A pair of parallel strands that twist together about an axis

Back

double helix

Front

Basic structural unit of DNA. Examples: adenine, guanine, cytosine, thymine.

Back

nucleotide

Front

5 carbon sugars and phosphates linked together through chemical bonds to provide the structural framework for nucleotides
