Back

Pauling

Front

What is a pair of parallel strands that twist together about an axis called?

Back

double helix

Front

Which scientist provided clear x-ray crystallography images of DNA?

Back

Franklin

Front

What is the basic structural unit of DNA, examples include adenine, guanine, cytosine, and thymine?

Back

nucleotide

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

What are the four nitrogenous bases found in DNA?

Back

adenine, thymine, cytosine, guanine

Front

What is the role of DNA polymerase in DNA replication?

Back

It synthesizes new DNA strands by adding nucleotides to a growing chain.

Front

What is the significance of the double helix structure of DNA?

Back

It allows for the efficient storage of genetic information and the mechanism for replication.

Front

What are complementary base pairs in DNA?

Back

Adenine pairs with Thymine, and Cytosine pairs with Guanine.

Front

What is Chargaff's rule?

Back

In any given DNA molecule, the amount of adenine equals thymine, and the amount of cytosine equals guanine.
