Flashcards in Structure of DNA Deck (10):
Who discovered the structure of DNA?
Francis Crick and James Watson
What four nucleotide bases make up DNA?
Thymine, Guanine, Adenine, Cytosine
What type of unique structure does DNA have?
How was the structure of DNA discovered?
The work of Rosalind Franklin, who used X-Ray diffraction to get a closer look at DNA, would lead to the discovery of the structure of DNA by Francis Crick and James Watson. Francis Crick and James Watson presented a model of DNA as a double helix structure; they figured out that the structure had a smooth sugar-phosphate backbone with two pieces of equal length that latched together with separate yet specific base pairs (Ex. Thymine-Adenine, Cytosine-Guanine).
What does 'DNA' stand for?
What three parts make up a nucleotide?
A sugar, a phosphate, and a base
What is a nucleoside?
A molecule made up of one of the four DNA bases covalently bonded to a sugar
Two carbon nitrogen ring bases (Adenine & Guanine)
One carbon nitrogen ring bases (Thymine & Adenine)
