What is one advantage of using allele-specific oligonucleotide probes over restriction enzymes for distinguishing an individual's genotype?a.They can detect any single base substitution, whereas restriction enzymes detectb.substitutions only at specific restriction sites. Unlike restriction enzyme analysis, they do not require the use of radioactive isotopes.c. The probes can detect a point mutation and also excise the chromosome segment in which the mutation is located.d. They do not require a cell sample from the individual.
