background image Review Questions  BSC108 CH 9-12  DNA contains the sugar Deoxyribose, while RNA contains the sugar ribose. i. DNA is double stranded while RNA is single ii. DNA is responsible for storing and transferring genetic information, while RNA directly codes for amino 
acids.
iii. DNA ---> RNA ---> Protein iv. Both Consist of chemical units called nucleotides v. The nucleotides are joined by a sugar-phosphate backbone vi. Adenine (A) 1) Thymine (T) 2) Guanine (G) 3) Cytosine © 4) The Four nucleotides found in DNA vii. In RNA T is replaced with Uracil (U) viii. What are the differences between RNA and DNA? 1. May result from, errors in DNA replication DNA can be damaged by ultraviolet light Physical or chemical agents called mutagens (specifically change your DNA as opposed to carcinogens 
which give way to a change)
Mutation- any change in the nucleotide sequence of DNA i. What is a mutation? What can cause a mutation? 2. DeoxyriboNucleic Acid i. RiboNucleic Acid ii. What is the full name for DNA? RNA? 3. Know where the sugar, phosphates, and nucleotides are located on the double helix. 4. • DON’T BE LATE!! Test Monday at either 5 or 6:20 depending on your section Study Guide Exam 3- Chapters 9-12 Wednesday, November 2, 2016 9:45 AM     BSC 108 Page 1    
background image The type of change Where the change in DNA occurs If the change is detected and fixed before replication How it affects the organism and its survival Mutations can be good, bad, or result in no change depending on: Mutations are the basis of cancer (Bad), many genetic diseases (Bad), evolution (Good), and rich diversity 
(Good)
How can a mutation be good, bad or cause no obvious difference? 5. Watson and Crick i. Who won the Nobel Prize for the structure of  DNA? 6. Watson and Crick decided DNA replicates by a template mechanism  a. Begins at specific sites on a double helix i. Proceeds in both directions ii. Dozens of enzymes are used to make the covalent bonds and to keep the DNA unzipped etc. iii. Fast and quite accurate iv. Only about 1 in 1 billion bases is incorrectly paired, but that one can lead to mutations v. DNA Replication b. DNA Replication i. What is replication? 7. Happens first i. In the nucleus  ii. DNA turn into RNA iii. Transcription  i. What is transcription? 8. When the newly formed RNA turns into protein. i. What is translation? 9. Replication and transcription- Nucleus i. Translation- Cytoplasm ii. Where does replication, transcription and translation take place? 10. Protein function relies on the correct sequence of DNA. i. Therefore, a mutation in the DNA will cause a protein to not function correctly ii. How can a mutation in the DNA result in a protein not functioning correctly? 11. What is a mutagen? Know some examples of mutagens. 12.     BSC 108 Page 2
