By the end of this activity you should be able to:
2. Identify and draw the three parts of a nucleic acid.
1. Explain what (and where) genetic information is.
LICATION
3. Explain the basic structures, processes, and steps involved in DNA replication.
4. Identify leading and lagging strands in a replication fork and bubble.
5. Know the enzymes involved in DNA replication, and predict the result of their
malfunctioning.
PART 1: DNA STRUCTURE
Nucleotides are the building blocks of nucleic acids (RNA and DNA).
1. On the nucleotide schematic below:
A. label the phosphate group, the nitrogenous base, and the pentose (5-carbon
sugar).
B. Label the carbon atoms in the sugar ring from 1 to 5.
H

CH
C. What functional groups on ANY nucleotide can tell you whether it is a
component of DNA or RNA?
D. Which carbon # is this functional group bound to?
E. What functional group does the 3' on DNA represent?
F. What functional group does the 5' on DNA represent?
