EBIO 2070 Final Exam 2024
Clicker Qs questions and
answers(graded A+)
What type of chromosome structure mutation could produce a phenotype
that mimics a trisomy?
a) Translocation
b) Inversion
c) Duplication
d) Deletion (with no duplication)
e) More than one answer is correct - answer E: C+D
which where small, covered in fur, and lacked horns. Assuming the
KERATIN GENE diagram below is correct, what type of mutation(s)
was(were) most likely associated with the evolution of modern rhinos?
a) L.O.F. in keratin exons
b) G.O.F. in keratin exons
c) L.O.F. and/or G.O.F. in the keratin promoter
d) L.O.F. and/or G.O.F. in keratin enhancers
e) L.O.F. and/or G.O.F. in a T.F. that activates keratin. (TOO PLEIOTROPIC) -
answer D
Between you and any member of this class, you have about one DNA
sequence difference (who is the mutant?) for every 1000 bp. Only a small
fraction of these are functional differences, i.e. mutations that result in
phenotypic differences between you and your classmate. Based on what
you know about mutations,most of these differences are likely to be:
a) Null mutations
b) Gain of function mutations in protein coding exons
c) Partial loss of function mutations in protein coding exons
d) Partial loss of function mutations in CREs
