A feature of organic compounds NOT found in inorganic compounds is the presence of
Correct answer-carbon atoms covalently bonded to each other
A student analyzed a viral genome and found that the genome had the following nucleotide
composition.
• 28% adenine
• 20% thymine
• 35% cytosine
• 17% guanine
Which of the following best describes the structure of the viral genome? Correct answer-
single-stranded DNA
The CFTR protein is made up of 1,480 amino acids linked together in a chain. Some humans
produce a version of the CFTR protein in which phenylalanine (an amino acid) has been deleted
from position 508 of the amino acid chain.

Solutions
Which of the following best predicts how the amino acid deletion will affect the structure of the
CFTR protein? Correct answer-It will affect the primary, secondary, and tertiary structures
of the CFTR protein.
Bacteriophages are viruses that infect bacteria. In an experiment, bacteriophages were labeled
with either radioactive phosphorus or radioactive sulfur. The labeled bacteriophages were
incubated with bacteria for a brief amount of time and then removed. The infected bacteria
cells were found to contain significant amounts of radioactive phosphorus but not radioactive
sulfur.
Based on the results of the experiment, which of the following types of molecules did the
bacteriophages most likely inject into the bacteria cells? Correct answer-DNA
The carbohydrates glucose, galactose, and fructose have the same chemical formula (C6H12O6)
but different structural formulas, which of the following statements about glucose, galactose,
and fructose is most likely true? Correct answer-The carbohydrates have different
properties because they have different arrangements of carbon, hydrogen, and oxygen atoms.
Which of the following statements best describes how organisms such as rabbits obtain the
carbon necessary for building biological molecules? Correct answer-Rabbits eat plants
and break down plant molecules to obtain carbon and other atoms that they rearrange into
new carbon-containing molecules.
