A particular chromosome has the normal gene sequence
A B C * D E F G H I
(where the * is the centromere). Which of the chromosomes shown below could arise if
this chromosome went through a reciprocal translocation event?
a) A B C * G H I
b) A B C * F E D G H I
c) A B C * D E E D * C B A
d) A B F E D * C G H I
e) A B C * D E F G M N O P Q R S
In a complementation test, if the combination of two recessive mutations that cause the
same phenotype results in that mutant phenotype, then the mutations are regarded as
a) pleiotropic
b) codominant
c) alleles of different genes
d) alleles of the same gene
e) epistatic
Consider the restriction sites recognized by the following restriction enzymes (where 'N'
indicates any of the four bases at that position, 'R' indicates any purine, 'Y' indicates any
pyrimidine):
TaqI TCGA
MaeIII GTRAC
KpnI GGTACC
MueI RCCCGGGY
NotI GCGGCCGC
Assuming a species genome that is 25% each of the four bases, which of these
restriction enzymes would you use if you wanted to randomly digest that genome into
DNA fragments of the smallest average size?

b) MueI
c) MaeIII
d) KpnI
