Final answer:
EIA, RT-PCR, and PCR are all techniques that can detect the presence of a specific virus. They use distinct methods involving antigen/antibody detection and genetic material amplification.
Step-by-step explanation:
The techniques that can be used to detect the presence of a specific virus are Enzyme Immunoassay (EIA), Reverse Transcription Polymerase Chain Reaction (RT-PCR), and Polymerase Chain Reaction (PCR). All of these methods are capable of identifying a virus, but they do so in different ways:
- EIA is a method that detects antibodies or antigens to diagnose viral infections.
- RT-PCR is a technique that first transcribes RNA into DNA and then amplifies specific DNA sequences associated with the virus.
- PCR amplifies the DNA of a virus, making it easier to detect even small amounts of viral genetic material.
All of the above techniques (A, B, and C) use native IPv6 connectivity to carry out their function when networked systems and devices are involved.
