an acentric chromosome fragment is produced by … Question An
acentric chromosome fragment is produced by recombination between a
rearranged and normal homolog in which of the following? partial
chromosome duplication paracentric inversion pericentric inversion
reciprocal translocation Which of the following statements about IS
(insertion sequence) elements is false? IS elements carry only the
genetic information necessary for their own transposition. IS
elements include inverted terminal repeat sequences on each side of
a transposase gene. IS elements generate mutations by insertion
into genes. Transposition of IS elements requires expression of
transposase encoded outside of the IS element. A mating between a
male donkey (2n = 62) and a female horse (2n = 64) produces sterile
mules. However, you recently observed a rare event: a female mule
gave birth to an offspring mating with a horse. Why are mules
sterile? How many chromosomes are in mules? How many chromosomes
are in the offspring? Why won’t this mule-horse offspring exhibit
fully horse-like characteristics? A given chromosome has the
following segments: A B C D E • F G H I J where • represents the
centromere. Which of the following represents a single paracentric
inversion? F G H I J • A B C D E A B C D E • F H I G J A D C B E •
F G H J I A B C H G F • E D I J Which of the following sequences of
DNA is most likely to be found flanking an insertion sequence (IS)?
