This is the enzyme that "unzips the DNA"

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

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

200
The four nucleotide bases
What are Adenine, Thymine, Guanine, Cytosine?
200

Step 2

RNA primase adds a primer to lagging strand

200

Needs many primers

What is the lagging strand

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 partnering of nucleotide bases on DNA ...
What is A=T, G=C
300

Step 3

DNA polymerase adds complimentary bases from 5' to 3' end on leading strand

300
Copies in the 3' to the 5' direction
What is the lagging strand?
300

DNA shape was described by_________and inspired by

Watson and Crick and inspired by Rosalind Franklin

400

The enzyme that does the proofreading

What is DNA Polymerase 

400

Nucleotide is made of

sugar, base and phosphate group

400

Step 4

DNA polymerase III adds complimentary bases in the 5' to 3' direction, forming Okazaki fragments

400
Forms Okazaki fragments
What is the lagging strand
400

Meaning of semi conservative

the mechanism by which DNA replicates in all known cells, producing two copies that each contain one original (template) strand and one newly synthesized strand 

500
This tells the DNA polymerase to begin adding new bases to the template LAGGING strand?
What is RNA primase?
500

What makes backbone of DNA

sugar and phosphate

500

Step 5

DNA ligase links Okazaki fragments. You end up with 2 strands "daughter" of DNA from 1 "parent" strand

500
Forms a new "daughter" strand of DNA by using the "parent" strand as a template
What is BOTH!
500

Two strands of DNA are said to be _________ to each other

anti parallel
