Leading, Lagging, or Both?
100

This is the enzyme that "unzips the genes"

Helicase

100

This is the word for the shape of DNA

Double-helix

100

Step 1

What is helicase unzips the genes, forms a replication fork

100

Template strand direction: 5′ → 3′

Lagging strand

200

This is the enzyme that adds new nucleotide bases to the parent or template strand to form a new DNA strand

DNA Polymerase III

200

The four nucleotide bases

Adenine, Thymine, Guanine, Cytosine

200
Step 2
DNA polymerase adds complimentary bases from 5' to 3' end on leading strand
200

Uses Helicase, DNA Polymerase III & I, RNA primase, and DNA ligase

 lagging strand

300

This is the enzyme that links all the bases on the lagging strand together

DNA Ligase

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

Step 3

RNA primase adds a primer to strand

300

Template strand direction: 3′ → 5′

Leading strand

400

The enzyme that replaces the RNA primers on the lagging strand?

Polymerase I

400
These are the fragments formed on the lagging strand by DNA Polymerase III.
What are Okazaki fragments?
400

Step 4

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

400

Which strand forms Okazaki fragments

 Lagging strand

500

This tells the DNA polymerase to begin adding new bases to the template strand?

 RNA primase

500

The difference between RNA (ribonucleic acid) and DNA (DEOXYribonucleic acid)

 oxygen molecule

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

BOTH!
