- What did Franklin/Wilkins use to help decipher the shape of DNA?
- X-Ray diffraction
- He discovered that A=T and C=G
- Chargoff
- This Scientist was trying to figure out if the tranforming substance was protein, carbohydrates or DNA. Who was it?
- Avery
- He found that when heat killed smooth bacteria and living rough bacteria were injected into a mouse, something caused the rough bacteria to turn into smooth bacteria. Who was it?
- Griffith
- Griffith did not realize it at first but he discovered this?
- The transformation in bacteria.
- Hershey/Chase found that DNA was the molecule that a virus injected into what?
- Its host.
- Is the R-Strain of pneumonia virulent or not virulent?
- Not virulent
- The mice died when this was injected into them?
- Heat killed smooth form pneumonia and living rough form Pneumonia
- Transformation did not occur when heat killed smooth and rough bacteria with DNA destroying enzymes was used in an experiment, True or False?
- True
- Protein coat and DNA are the two parts of this?
- Virus
- Radioactive labeled DNA were found inside the bacteria after the virus infected the bacteria, True or False
- True
- A=T and C=G is who's rule?
- Chargoff's rule
- They built a model of DNA with the configuration of a double helix, who were they?
- Watson and Crick
- Watson and Cricks DNA model was formed on the basis of another Scientist work, who was it?
- Chargoff
- Nucleotide is the monomer of a _____________.
- Nucleic acid
- Ribose is or is not a part of DNA?
- Is not
- We study DNA for these three reasons.
- Cloning, Stem Cell Research, Cure/Prevent diseases
- These weak H-Bonds hold strands of this together. What is it.
- DNA
- In a eukaryote cell what is found in the nucleus?
- A strand of DNA

- RNA
- This helps wind up and package eukaryotic DNA, what is it?
- Histone
- What is the process of Transcription?
- Instructions for making a protein transfer from a gene to an RNA molecule
- How many codon combinations are there?
- 64
- These instructions are written as a series of three-nucleotide sequences called codons is it RNA or DNA?
- RNA
- What is the process by which the nucleotides in mRNA are decoded into a sequence of amino acids?
- This is the purpose of translation.
- Where does translation occur at?
- Ribosome
- In the DNA extration lab this element destroyed the cell and nuclear membranes. What was it?
- Tide detergent
