The components of the backbone.
What are sugar and phosphate?
100
The outcome of Watson and Crick's research.

100
The enzymes active during replication.
What is DNA polymerase I and III, helicase, and ligase?
100
The location of translation.
What is ribosome?
100
Three differences between DNA and RNA.
What is DNA is double stranded, contains Thymine, and has a deoxyribose sugar; RNA is single stranded, contains Uracil, and has a ribose sugar?
200
The components of a nucleotide.
What is a sugar, phosphate, and nitrogenous base?
200
The outcome of Franklin and Wilkin's research.
What is they used x-ray diffraction to conclude that DNA was a double helix?
200
Leading v. lagging strand.
What is leading strand is continuously replicated from 5' to 3' end and lagging strand is replicated in sections(okazaki fragments) in the 5' to 3' end with the help of RNA primase?
200
The location of transcription.
What is the nucleus?
200
The definition of a codon.
What is a sequence of three nitrogenous bases that code for a particular amino acid?
300
Purines v. pyrimidines (which bases and how many rings)
What is purine= Adenine and Guanine 2 rings and pyrimidines= Cytosine and Thymine 1 ring?
300
The outcome of the Hershey and Chase experiment.
What is DNA is the genetic carrier not proteins?
300
The function of the SSBs.
What is stabalize DNA and keep the two strands from sealing back together?
300
The outcome of transcription.
What is a strand of mRNA containing intsrutctions of how to make a particular protein?
300
Switching a G to a C in a DNA sequence.
What is a point mutation?
400
Complementary base pairs for DNA.
What is Adenine binds with Thymine and Guanine binds with Cytosine?
400
The meaning of DNA
What is deoxyribonucleic acid?
400
The meaning of DNA polymerase.
What is polymer- putting many pieces together and ase- enzyme (DNA polymerase adds bases [nucleotides] to the strand)?
400
The outcome of translation.
What is a polypeptide chain bound together through peptide bonds?
400
Frameshift mutation.
What is inserting or deleting a base in a DNA sequence causing a disruption to the protein sequence?
500
The structure and function of nucleosomes.
What is DNA wrapped around histones to keep the DNA from tangling and allow it to fit in the nucleus which creates a chromosome?
500
The effect of adding detergent, meat tenderizer, and alcohol for DNA extraction.
What is to release the DNA by breaking apart the cell membrane (detergent), cuts up the histones and allows DNA to unwind (meat tenderizer), reduces the solubility of DNA allowing it to be visible in the test tube (alcohol)?
500
The process of DNA replication (in order).
What is 1. helicase unzips the DNA, 2. SSBs bind to each strand of DNA to stabilize and seperate, 3. DNA polymerase attaches at the 5' end and begins adding complementary bases to the leading strand continuously, and discontinuously on the lagging strand 4. SSBs are released. 5. ligase binds everything together, 6. two semi conservative strands of DNA result?
500
The function of DNA in transcription, and the function of mRNA and tRNA in translation.
What is DNA serves as a template to make an mRNA strand, and mRNA provides the instructions explaining how to make a protein and tRNA brings the amino acids to the ribosome to make the polypeptide chain?
500
Nonsense vs. missense mutation
What is premature stop causing a nonfunctional protein vs. an amino acid change creating a functional but different protein than desired? Both are types of point mutations.
