Misc.
100
This is the enzyme that "unzips the genes"
What is helicase?
100
This is the word for the shape of DNA
What is a double-helix?
100

Two repair strategies for double-stranded breaks

What is non homologous end joining and homologous recombination?

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

The spontaneous loss of an amino group from cytosine to produce uracil

What is deamination?

200

Uses Helicase, DNA Polymerase, Nuclease, and DNA ligase

What is the lagging strand

200

Two catalytic domains of DNA polymerase

What are the polymerizing and editing domains?

300

Forms a phosphodiester bond between the 5’ phosphate of one DNA fragment with the adjacent 3’ OH of the next

What is DNA Ligase?

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

The first step to DNA damage repair

What is Damaged DNA is recognized and removed by nucleases

300

Copies in the 3' to the 5' direction

What is the lagging strand?

300

Model of DNA replication where parental and newly synthesized strands become randomly mixed during the replication process 

What is dispersive DNA replication?

400

RNA polymerase that synthesizes RNA primer required for initiation of DNA replication

What is Primase?

400

100 to 2000 nucleotide fragments formed in discontinuous replication

What are Okazaki fragments?

400

The second step to DNA damage repair

Repair DNA polymerase binds free 3’ OH of cut DNA strand – fills gap

400
Forms Okazaki fragments
What is the lagging strand
400
After helicase unzips the genes, these hold the template strands of DNA in place so that they do not wind back up.
What are single-stranded binding proteins?
500

Produces breaks in the DNA molecules to prevent supercoiling and knot formation during replication, then rejoins

What is topoisomerase?

500
The difference between RNA (ribonucleic acid) and DNA (DEOXYribonucleic acid)
What is an oxygen molecule?
500

Two steps involved in DNA mismatch repair

What is 1. Removal of a portion of DNA strand containing mismatch 2. Resynthesize missing DNA

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

Covalent linkage between two adjacent pyrimidine bases, exposure to UV light

What are thymine dimers?
