Auburn BIOL 3001 Final Exam and
Correct Answers 2026-2027 Updated.
electrophoresis - Answer a series of techniques by which biomolecules can be separated
based on size, length, and/or shape
false - Answer True or False: you will be using a new computer program this week called ELS
which stands for Easy Learned Science
length - Answer The fragments of DNA we will be examining this week in lab will be separated
based on fragment _____ (shape, length, density, or configuration)
5 - Answer When using the ELS program, the samples should be heated for a minimum of
____ minutes
... (not enough resolution/separation of the band fragments if the gel runs too short making it
difficult to interpret and loss of data if bands are run off the end of the gel) - Answer Know
how to explain why it is so important to control the time of gel electrophoresis. What happens if
it runs too short of a time versus too long of a time.
autoradiography - Answer the final step in the ELS program is to "develop" the gel so that the
DNA fragments become visible. This technique uses a small amount of radioactive phosphorus
and is called ________
co-dominance - Answer The DNA fragments used in this will exhibit a very simple mode of
inheritance, which is ________ (simple Mendelian dominance, co-dominance, incomplete
dominance, sex-linkage, epistasis)
1, 2 - Answer because of the simple MOI it will be very easy to distinguish homozygotes from
heterozygotes during this lab exercise. Homozygotes will show ___ band(s), and heterozygotes
will show ___ band(s)
uncertainty exists in all scientific studies - Answer the genotyping that we will be using in the
exercise provides us with an example of how science can help solve a problem. Genotyping also
provides us with another critical lesson, namely that __________
a. science is the ONLY valid way to search for the "truth"
b. scientific proof is ALWAYS the expected outcome of a good experiment
