Points Possible
Total Points on Test
1. DNA structure-- Can draw and explain the structure of a DNA
molecule, matching the correct base pairs.
Key Terms:
Deoxyribonucleic acid
Nitrogen base
Adenine
Thymine
Cytosine
Guanine
Phosphate
Backbone
Double helix
Nucleotide
Key Concepts:
 DNA is the largest macromolecule known, stretching up to 6 feet in length.
 DNA has a twisted ladder shape known as a double helix; the rungs are nitrogen
bases, the backbone is made of sugar and phosphate.
 Among the bases, adenine always pairs with thymine and cytosine always pairs with
guanine.
2. Replication-- Can explain replication, how DNA copies itself.
Key Term: Enzyme
Key Concepts:
 DNA makes an exact copy of itself.
 There are 4 steps in the process: unwind, unzip, free nucleotides fill in, and rewind.
3. Function--Can explain how sections of DNA, genes, can code for a
protein.
Key Terms:
Gene
Chromosome
Protein
RNA
Key Concepts:
 A chromosome is a continuous strand of DNA.
 A gene is a section of DNA which has the code for one protein.
 RNA carries the recipe for the gene to ribosomes where the proteins are made.
