DNA

The two bases that are purines are:

Adenine Guanine

The bases are paired by _________ bonds along the axis of the molecule.

hydrogen

Two scientist are give credit for discovering the structure of DNA. What is the name of those two scientists?

Franklin Watson and Crick

This is called complementary base pairs. Thus one strand of DNA is complementary to the other strand (opposite/matching.)

Matching

Wilkins and Franklin studied the structure of DNA using __________, a technique to examine molecule, and helped Watson and Crick determine that the shape of the molecule was a _____________ __________.

X-ray crystallography double helix

The "backbone" of the DNA molecule is made up of two components, what are these?

one phosphate group deoxyribose sugars

These bases are of two different types of molecules: purines and pyrimidines. Purines have_________ring(s) in their structure, and pyrimidines have __________ring(s) in their structure.

smaller larger

What do the letter DNA stand for?

Deoxyribose nucleuic acid.

There are four different variations of these monomers (four different bases), what are the names of those bases?

Adenine Guanine Cytosine Thymine

Based on this information, scientists could predict that the base ________ pairs with ________ and the base ________ pairs with _______ in the formation of the DNA molecule.

Adenine Thymine Guanine Cytosine

Chargoff's rule states that the DNA of any species contains equal amounts of __________ and also equal amounts of ________ and ___________.

Adenine Thymine Guanine Cytosine

The two bases that are pyrimidines are:

Cytosine Thymine

DNA is a polymer, which means that it is made up of many repeating single units (monomers). What are the monomers called?
