100
This is the enzyme that "unzips the genes"
What is helicase?
100
This is the word for the shape of DNA
What is a double-helix?
100
Step 1
What is helicase unzips the genes, forms a replication fork
100
Copies from the 5' to the 3' end of the old strand
What is the leading strand
100
The name of the area where DNA begins to replicate/copy/divide
What is the replication fork?
200
This is the enzyme that adds new nucleotide bases to the parent or template strand to form a new DNA strand
What is DNA Polymerase III
200
The four nucleotide bases
What are Adenine, Thymine, Guanine, Cytosine?
200
Step 2
Primase lays down RNA Primers on each strand
200
Uses Helicase, DNA Polymerase III & I, RNA primase, and DNA ligase
Both
200
The complimentary strand to a template DNA strand that reads "CAT TAC GCT"
What is "GTA ATG CGA"?
300
This is the enzyme that links all the bases on the lagging strand together
What is DNA Ligase?
300
The base pairing rule says....
What is A=T, G=C
300
Step 3
DNA Polymerase 3 adds new DNA to each strand
300
Copies in the 3' to the 5' direction of the old strand
What is the lagging strand?
300
sugar, phosphate, base
What is a nucleotide?
400
The enzyme adds the RNA primers on the lagging strand?
What is Primase
400
These are the fragments formed on the lagging strand by DNA Polymerase III.
What are Okazaki fragments?
400
Step 4
Ligase glues the Okazaki fragments together
400
Forms Okazaki fragments
What is the lagging strand
400
Part of Interphase that involves DNA Replication
S-phase
500
Any word that ends in -ase
Enzyme
500
The difference between a purine and pyrimidine
What is a purine has 2 rings and a pyrimidine has 1 ring
500
Step 5
2 sets of DNA separate leaving 2 identical copies of DNA
500
Forms a new "daughter" strand of DNA by using the "parent" strand as a template
