Some genetic diseases cannot be diagnosed by changes in restriction sites. Some of these can be detected by allele-specific oligonucleotide probes. These are

copies of the gene with an altered sequence so that a restriction site is inserted
mutagenized copies of a gene
PCR-amplified variable numbers of tandem repeats (VNTRs)
short sequences that will hybridize only to a specific base sequence

contains DNA for virtually all of the human proteins in vectors
cannot be used to obtain human genes because it would be radioactive
None of these
contains DNA for specific human proteins
