BIOL 204 Study Guide Exam Graded A+ 2026
1
The search for natural explanations of natural phenomena is known as:
Science
2
Which of the following are qualities of any good scientific hypothesis?
I. It is testable.
II. It is falsifiable.
III. It produces quantitative data.
IV. It produces results that can be replicated.
I. It is testable
II. It is falsifiable
3
Agrobacterium infects plants and causes them to form tumors. You determine that
tumor formation requires a large amount of the plant's energy for tissue formation.
How might this change the number of offspring a plant produces, and what is the
most likely explanation for this change?
The number of offspring should decrease because the plant will divert energy from
reproduction to tumor formation.
4
A heat-killed, phosphorescent (light-emitting) strain of bacteria is mixed with a living,
non-phosphorescent strain. Further observations of the mixture show that some of
the living cells are now phosphorescent. Which of the following observations would
provide the best evidence that the ability to phosphoresce is a heritable trait?
phosphorescence in descendants of the living cells
5
Which of the following provides evidence of the common ancestry of all life?
near universality of the genetic code
6
Which of the following statements accurately describes the structure of a eukaryotic
chromosome?
It is a single linear molecule of double-stranded DNA plus proteins.

As letters are to English language, ________ is/are to genetic information.
nucleotides
8
You sequence the genome of a new plant. The new genome has 13.5% adenine. What
will be the cytosine content?
36.5%
9
What name is given to the process in which a strand of mRNA is constructed from a
sequence of nucleotides on a DNA molecule?
transcription
10
What will be the translation of the following mRNA?
5'-GUUGCUGAUGGU-3'
Val, Ala, Asp, Gly
11
The genetic code is essentially the same for all organisms. From this, one can logically
assume which of the following statements is most accurate?
A gene from an organism can theoretically be expressed by any other organism.
12
Hershey and Chase set out to determine what molecule served as the unit of
inheritance in organsims. They completed a series of experiments in which E. coli was
infected by a T2 virus. Which molecular component of the T2 virus actually ended up
inside the cell and thus transmits genetic information?
DNA
13
Why might the cricket genome have eleven times as many base pairs as that of the
fruit fly Drosophila melanogaster?
Crickets must have more noncoding DNA.
14
In a gene 3000 bp long, a substitution occurred in position 11 that resulted in the
change of a UUG to CUA. What type of substitution is this?
Silent
