In the whole-genome shotgun method, the genome is fragmented and individual fragments are
sequenced. How do we determine the order of the nucleotides in the intact chromosome?
a. The fragmentation is done in a very systematic way such that the physical arrangement of
fragments is readily apparent.
b. The sequence of the ends of the fragments overlap with the ends of other fragments.
c. We supplement our information with data from a different technique to determine the final
chromosome arrangement.
d. DNA hybridization assays are conducted to determine the physical arrangement of the
genes on the chromosome.
e. After sequencing, the fragments are labeled and used as probes in a Southern blot.
