DNA Replication Jeopardy

Enzymes

100

This is the enzyme that "unzips the genes"

What is helicase?

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

300

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

What is DNA Ligase?

400

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

What is Polymerase I

500

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

What is RNA primase?

Structures

100

This is the word for the shape of DNA

What is a double-helix?

200

The four nucleotide bases

What are Adenine, Thymine, Guanine, Cytosine?

300

The backbone of DNA

What are a phosphate group and a sugar

400

These are the fragments formed on the lagging strand by DNA Polymerase III.

What are Okazaki fragments?

500

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

What is an oxygen molecule?

Order of Processes

100

Step 1

What is helicase unzips the genes, forms a replication fork

200

Step 2

RNA Primase adds primers

300

Step 3

DNA Polymerase III adds nucleotides

400

Step 4

DNA polymerase I removes primers and creates Okazaki fragments

500

Step 5

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

Vocabulary

100

This term describes the process by which a DNA molecule is copied to create two identical DNA molecules.

What is DNA Replication

200

These short DNA fragments are synthesized on the lagging strand and are later joined together by ligase

What are Okazaki Fragments

300

This is the region where the two DNA strands are separated and replication begins.

What is the replication fork

400

This term refers to the overall direction in which DNA polymerase synthesizes new DNA strands.

What is 5' to 3' direction?

500

This molecule provides the starting point for DNA synthesis by creating a short RNA sequence.

What is an RNA primer?

Grab Bag

100

The name of the area where DNA begins to replicate/copy/divide

What is the replication fork?

200

The complimentary strand to a template DNA strand that reads "CAT TAC GCT"

What is "GTA ATG CGA"?

300

The 5 enzymes of DNA replication in the correct order

What is helicase, rna primase, DNA polymerase III, DNA polymerase I, ligase.

400

This rule states that in any given DNA molecule, the amount of adenine equals the amount of thymine, and the amount of cytosine equals the amount of guanine.

What is Chargaff's rule?

500

According to Chargaff's rules, if a DNA sample contains 30% Guanine and 20% Adenine, these are the percentages of the other two bases.

What are 30% Cytosine and 20% Thymine?
