DNA Replication

DNA Structure

100

This is the word for the shape of DNA

Double helix

200

The four nucleotide bases

Adenine, Thymine, Cytosine, Guanine

300

The pairing of nucleotide bases on DNA ...

A=T, G=C

400

This the type of sugar found in DNA

Deoxyribose

500

The type of bond between nitrogen base pairs

hydrogen bond

Enzymes

100

This is the enzyme that unzips the original DNA strand

helicase

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

300

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

Ligase 

400

The enzyme that replaces the RNA primers.

DNA polymerase I

500

This tells the DNA polymerase where to begin adding new bases to the template.

RNA Primase

Process of Replication

100

Step 1

helicase unzips the DNA Strand 

200

Step 2

Primers are built

300

Step 3

DNA polymerase III add nucleotides to the end of the primers

400

Step 4

DNA polymerase I removes RNA primers and replaces them with DNA nucleotides

500

Step 5

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

Leading, Lagging, or Both?

100

Made continuously

Leading strand

200

Made discontinuously

Lagging strand

300

Has okazaki fragments

Lagging strand

400

Only use one primer

Leading strand

500

Forms a new "daughter" strand of DNA by using the "parent" strand as a template

Both

Grab Bag

100

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

Nucleus

200

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

"GTA ATG CGA"?

300

After helicase unzips the genes, these hold the template strands of DNA in place so that they do not wind back up.

single-stranded binding proteins

400

Relieves tension caused helicase

Topoisomerase

500

This is formed as the two original strands of DNA part

Replication fork
