What are phosphate, sugar and a nitrogen base?
100
This enzyme unzips the double helix.
What is DNA helicase?
100
Fill in the blanks ___________ --> ___________ --> ___________
What is DNA to RNA to Protein?
100
Translation uses a mRNA blueprint to make this.
What is a protein? (or an amino acid chain)
100
Most mutations happen at this time since they are permanent changes in DNA.
What is during DNA replication?
200
The basic unit of DNA and RNA.
What is a nucleotide?
200
This enzyme joins the Okazaki fragments.
What is DNA ligase?
200
DNA uses thymine, while RNA uses this.
What is Uracil (U)?
200
This is the builder of the amino acid chain.
What is a ribosome?
200
Two types of point mutation that occur at one point in the DNA sequence.
What are substitution and nonsense mutations?
300
These people are credited with discovering the shape of DNA
Who are Watson and Crick?
300
This enzyme follows helicase and follows base pairing rules to make the complementary DNA strand.
What is DNA polymerase?
300
Transcription uses DNA to make a ___________ blueprint.
What is mRNA?
300
This RNA type carries the correct amino acids to the ribosome.
What is tRNA?
300
A mutation that throws off the entire amino acid sequence.
What is a frameshift mutation (deletion, insertion)?
400
The base pairing rules.
What is Adenine - Thymine and Guanine - Cytosine?
400
DNA replication occurs during this time.
What is the S phase of interphase?
400
This enzyme matches RNA bases to the DNA template.
What is RNA polymerase?
400
The start codon.
What is 'AUG'?
400
A mutation that can be passed on to offspring.
What is a sex-cell mutation?
500
The shape of the DNA molecule.
What is a double-helix?
500
This strand replicates continuously.
What is the leading strand?
500
We often call the mRNA copy this.
What is a blueprint?
500
UAA, UAG, or UGA.
