DNA Structure
This is the word for the shape of DNA
Double helix
This is the enzyme that unzips the original DNA strand
helicase
Step 1
helicase unzips the DNA Strand
Made continuously
The name of the area where DNA begins to replicate/copy/divide
Nucleus
The four nucleotide bases
Adenine, Thymine, Cytosine, Guanine
This is the enzyme that adds new nucleotide bases to the parent or template strand to form a new DNA strand
DNA Polymerase III
Step 2
Primers are built
Made discontinuously
Lagging strand
The complimentary strand to a template DNA strand that reads "CAT TAC GCT"
"GTA ATG CGA"?
The pairing of nucleotide bases on DNA ...
A=T, G=C
This is the enzyme that links all the bases on the lagging strand together
Ligase
Step 3
DNA polymerase III add nucleotides to the end of the primers
Has okazaki fragments
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
This the type of sugar found in DNA
Deoxyribose
The enzyme that replaces the RNA primers.
DNA polymerase I
Step 4
DNA polymerase I removes RNA primers and replaces them with DNA nucleotides
Only use one primer
Leading strand
Relieves tension caused helicase
Topoisomerase
The type of bond between nitrogen base pairs
hydrogen bond
This tells the DNA polymerase where to begin adding new bases to the template.
RNA Primase
Step 5
DNA ligase links Okazaki fragments. You end up with 2 strands "daughter" of DNA from 1 "parent" strand
Forms a new "daughter" strand of DNA by using the "parent" strand as a template
Both
This is formed as the two original strands of DNA part
Replication fork
