The 107 pages that link to Polymerase chain reaction, each with the reason it gives.

• KaryotypeCompared with: It tests targeted genetic regions rather than surveying whole chromosomes visually.

• Blood cultureCompared with: PCR can detect microbial genetic material without waiting for growth.

• Fluorescence in situ hybridizationCompared with: PCR amplifies DNA, whereas FISH shows where target sequences occur in cells.

• SerologyCompared with: PCR detects genetic material rather than the host's antibody response.

• Bacterial cultureCompared with: PCR can detect bacterial DNA without waiting for organisms to grow.

• Molecular cloningCompared with: PCR can amplify DNA directly without propagating it in a host vector.

• Viral replicationCompared with: PCR amplifies genetic material in vitro, unlike viral replication inside cells.

• Southern blotCompared with: PCR detects or amplifies chosen sequences without transferring genomic fragments to a membrane.

• Restriction fragment length polymorphismCompared with: PCR-based tests can work with much smaller DNA samples than traditional RFLP analysis.

• Stool antigen testCompared with: PCR detects genetic material rather than the pathogen proteins targeted by antigen assays.

• Stool cultureCompared with: Molecular assays can detect pathogens without requiring them to grow in culture.
