Question

Probes can come from a variety of sources,such as ____________________.
A) single-stranded RNA templates
B) histones from other species
C) artificially engineered gene sequences
D) related genes from other species
E) unrelated genes from other species

Accepted Answer

Probes can come from related genes from other species, as these genes may have some degree of homology with the target gene in the species of interest, allowing for hybridization and detection. Single-stranded RNA templates, histones from other species, and artificially engineered gene sequences may not be suitable as probes as they may not have the necessary homology to successfully bind to the target DNA. Unrelated genes from other species would also not be useful as probes as they would not have any homology with the target gene.
