200
Region where Helicase unwinds a strand of DNA.
Replication Fork
200
What is the first stage of protein synthesis what makes a copies of mRNA.
Transcription
200
DNA replication always happens in the ______ to ______ direction.
5' to 3'
200
Enzyme that binds or "glues" Okazaki fragments together on lagging strand of DNA replication.
Ligase
300
What are the three parts that make up a nucleotide.
Phosphate, Sugar, Nitrogenous Base
300
Fragments that form on the lagging strand of DNA replication.
Okazaki Fragments
300
Protein factories
Ribisomes
300
Why does a copy of mRNA need to be made for the process of protein synthesis to take place.
It is small enough to fit out of the nucleus, where DNA is not.
300
If the two sides of a strand of DNA are anti-parallel, it means what about them.
The run in opposite directions
400
The sides of the double helix are called the DNA ____________________.
Backbone
400
Enzyme that plugs in complementary bases on the developing strands of DNA. 
DNA polymerase
400
Three base sequences that code for a specific amino acid that are found on mRNA.
Codons
400
Second stage of protein synthesis where mRNA is read and used to make a chain of amino acids.
Translation
400
Where do transcription and translation take place?
In the nucleus and in the cytoplasm (on a ribosome)
500
What attractive force, found between the nitrogenous bases, holds the two sides of a strand of DNA together?
Hydrogen Bonds
500
The strand of DNA replication that copies much faster than the other.
Leading Strand
500
The fetchers of amino acids within the cytoplasm. Bring that amino acids back to the ribosomes to be attacked to the growing chain.
tRNA
500
Amino acids are monomers for the polymer _________________.
Proteins

When does DNA replication take place?
During interphase in the S phase
