Copying from other students or from outside resources will result in a zero on the accompanying lab quiz. I. DNA Structure 1. Which two scientists are credited with discovering DNA? ANSWER: James Watson and Francis Crick 2. Name the nitrogen bases that are pyrimidines. ANSWER: Cytosine and Thymine 3. Which nitrogen base pairs with cytosine? ANSWER: Guanine 4. A 5-carbon sugar, nitrogen base, and a phosphate group make up a ANSWER: deoxyribose sugar. II. DNA Replication 1. How many times does replication occur in the life of a cell? 2. Briefly describe the process of replication. 3. In the lab, Exercise 2, the original strand on the left had the bases shown below. Input the new bases that correctly pair with the original strand. Original New C A G T III. RNA Structure 1. List three ways RNA and DNA differ. ANSWER: © 2016 Access Learning Systems SP22 1 2. Refer to Exercise 3 and record the bases of the RNA strand that is produced from the replicated DNA strand. DNA RNA C A G T 3. Which nitrogen base is not found in RNA? IV. RNA Synthesis 1. How is transcription different from replication? 2. 3. Name three types of RNA. ANSWER: 4. Refer to Exercise 4. Write the letters for the base sequence of mRNA in the spaces below DNA. Note that the order is reversed; start with the 3’ end of the DNA strand and the 5’ end of the mRNA strand. Transcription is DNA to mRNA. Note RNA contains Uracil instead of Thymine; There is no thymine in RNA. DNA 3’ mRNA 5’ V. C G T C G T C C A A T T 5’ 3’ Protein Synthesis 1. Where in the cell does translation take place? 2.
