Early scientists thought this was the likely genetic material due to its complexity.
What are proteins?

DNA stands for this.
What is deoxyribonucleic acid?
200
These 2 men are credited with discovering the structure of DNA.
Who are Watson and Crick?
200
The enzyme that synthesizes the RNA Primer.
What is primase?
200
The sugar deoxyribose is referred to as this because of the number of carbons it has.
What is pentose (5 carbons)?
200
The "Y-shaped" region on DNA where the 2 strands of DNA separate during replication.
What is the replication fork?
200
The complementary DNA strand for the following DNA sequence: 5’-CGTATG-3’
What is 3’-GCATAC-5’ ?
300
His experiment showed transformation of genetic material between nonvirulent and virulent strains of bacteria suggesting some hereditary factor was serving as genetic material.
Who is Griffith?
300
This enzyme adds the new nucleotides during DNA replication?
What is DNA polymerase?
300
Most DNA is twisted this way.
What is a right handed twist?
300
This strand of DNA during replication is synthesized as a single strand from the point of origin toward the opening replication fork.
What is the leading strand?
300
This enzyme joins the Okazaki fragments together to make one strand.
What is ligase?
400
She was responsible for the X-ray crystallography photographs that helped Watson and Crick with their elucidation of the structure of DNA.
Who is Rosalind Franklin?
400
This enzyme unwinds and separates the 2 DNA strands by breaking the weak hydrogen bonds.
What is helicase?
400
A nucleotide is made up of these three parts.
What is a phosphate group, deoxyribose (a pentose sugar), and a nitrogenous base (A, T, C, or G).
400
This strand of DNA is synthesized discontinuously against the overall direction of replication in many short segments.
What is the lagging strand?
400
DNA replication is referred to as this because the two strands of the parental molecule separate, and each acts as a template for a new complementary strand.
What is semi-conservative?
500
This person has a rule named after him for figuring out the relative abundance and pairing rules for the four nitrogenous bases in DNA
Who is Chargaff?
500
This enzyme attaches to the 2 forks of the bubble to relieve stress on the DNA molecule as it separates.
What is topoisomerase?
500
3 hydrogen bonds bind these 2 base pairs together.
What is Cytosine and Guanine (C and G)?
500
The series of short segments on the lagging strand of DNA during DNA replication.
What are Okazaki fragments?
500
The error rate in base pairs goes from 1 in 10,000 to this once proofreading has occurred.
