Biology - Chapter 9 Study Guide (DNA)
1. Define vaccine.
Substance that is prepared from killed or weakened diseased causing agents
2. What is the name of the scientist that performed transformation experiments?
Griffith
Name the living organisms used in these experiments. mice 3. What is transformation?
A change in the genotype caused when bacterial cells take up foreign genetic material
4. Who discovered what material was responsible for transformation? What is the material?Oswald Avery DNA
5. Why was the Hershey-Chase experiment performed? What was the outcome of the experiment? To determine if protein or DNA caused change DNA derermines the transfer
6. What does DNA stand for? Deoxyribonucleic acid
7. How did Watson and Crick …show more content…
What are the four nitrogen bases? Which pairs always go together in a DNA molecule? adenine thymine cytosine guanine
9. What is the difference between a purine and a pyrimidine? The rings of carbon
10. Hydrogen bonds hold together nitrogen bases in which hold together the two strands of DNA.
11. Chargaff contributed to the discovery of DNA how?
The amount of adenine always equaled thymine and the amount of cytosine always equaled guanine
12. Wilkins and Franklin contributed to the discovery of DNA how?
Founded that DNA molecules ensemble a tightly coiled helix and is composed of 2 to 3 chains of nucleotides
13. What are the three base pairing rules?
Purine is always paired with a pyrimidine
Adenine always pairs with thymine A-T
Cytosine always pairs wit guanine C-G
14. How many hydrogen bonds are present between A-T? C-G? a-t is 2 c-g is 3
15. Be able to determine complementary base pairs in DNA.
1. TTACGATCC AATGCTAGG 2. AACGGTCGA TTGCCAGCT 3. CGATAGCAT GCTATCGTA
16. What is DNA replication?
Process of copying DNA
17. Give the name of the enzyme that breaks the hydrogen bonds between nitrogen bases during DNA
