Slipped-strand Mispairing

View the animation below, then complete the quiz to test your knowledge of the concept.






1During slipped-strand mispairing, homologous chromosomes
A)do not pair up with each other.
B)pair up normally with each other.
C)pair up with each other, but then they are both degraded.
D)pair up with each other, but out of register.
E)pair up with different homologous chromosome pairs.



2Slipped-strand mispairing may cause deletions resulting in
A)transposition.
B)inhibition of translation.
C)a frameshift mutation.
D)a single base substitution.
E)chromosome inactivation.



3Slipped-strand mispairing requires that a DNA sequence be present
A)in one copy on a homologous chromosome but no copies in the other.
B)in two copies on a homologous chromosome but no copies in the other.
C)in multiple copies on a homologous chromosome but no copies in the other.
D)in only a single copy on both homologous chromosomes.
E)in multiple copies on both homologous chromosomes.



4The loop formed during slipped strand mispairing may be excised by the cell’s repair enzymes.
A)True
B)False



5Some chemicals can stabilize these loops and thus decrease the time the loops are vulnerable to excision.
A)True
B)False
