TRUE or FALSE STRIPS
ROUND 1
1. Nucleic acids are a type of protein.
2. The monomer of proteins is an amino acid.
3. In Griffith’s experiment, the R strain was deadly and the S strain was harmless.
4. RNA is single stranded, whereas DNA is double stranded.
5. In transformation, one strain of bacteria is changed into another strain by genes.
6. Frederick Griffith studied bacteria that can cause pneumonia.
7. When Griffith injected living R strain with dead S strain, the mouse survived.
8. Rosalind Franklin used Watson & Crick’s data to propose the “double helix” model of DNA.
9. According to Chargaff’s rule, the amount of adenine (A) is equal to the amount of guanine (G).
10. Usually, DNA is found in the form of chromatin, not chromosomes.
11. A person’s genome is an organism’s complete set of cells.
12. DNA is stored like this: DNA + histones  nucleosomes  super coil  chromosomes.
13. Bacteriophages infect viruses.
14. In eukaryotes, there are many origins of replication.
Directions: Sort the given statements into those that are true and those that are false by writing the statements’
corresponding numbers in the columns below. WRITE THE NUMBERS IN CONSECUTIVE ORDER. You will have
as many true statements as false statements. At the bottom of the chart, choose two false statements and
correct them to make them true. Show Ms. Nguyen when you are done.
True Statements
1. Corrected Statement:
2. Corrected Statement:

ROUND 2
1. The double helix is the structure of DNA.
2. Complementary bases means they are exactly the same.
3. Adenine pairs with uracil in DNA replication.
4. DNA polymerase is an enzyme.
5. DNA helicase is an enzyme.
6. DNA helicase adds free-floating bases to the new strand of DNA during replication.
7. In RNA splicing, exons are removed.
8. DNA helicase “unzips” the molecule of DNA.
9. Transcription only copies genes that are needed, not a whole DNA molecule.
10. A promoter sequence tells RNA polymerase where to stop transcribing.
11. There are 30 different types of amino acids.
12. The Central Dogma states that genetic information flows as follows: DNA  mRNA  Protein
13. RNA stands for “Ribonucleic Acid”
14. 3 bases in a DNA molecule are a CODON.

1. One of the things that proteins do is repair our bodies.
2. DNA stands for “Deoxyribonucleic acid”
3. One of the functions of nucleic acids is to give us energy.
4. A lot of polymers put together would make a monomer.
5. If DNA is made up of monomers, then DNA itself would be considered a polymer.
6. The monomer of DNA is a nucleic acid.
7. A nucleotide consists of three main parts.
8. During transcription, only one strand of DNA is copied.
9. Adenine is a pyrimidine.
10. Uracil is found only in RNA.
11. Cytosine is a purine.
12. Names of enzymes usually end in the suffix “–ase”.
13. DNA is the instructions for making lipids.
14. During protein synthesis, genetic information from DNA travels from the nucleus to the cytoplasm.
15. The organelle known as a “protein factory” is called the mitochondrion.
16. The nitrogenous bases in the middle of a DNA molecule are linked by covalent bonds.
