|
Answer» |
|
| 20017. |
Question : Can a disease be detected before its symptoms appear ? Explain the principle involved. |
| Answer» Solution :Presence of a PATHOGEN (bacteria, viruses, etc.) is normally suspected only when the pathogen has produced a disease symptom. By this time the concentration of pathogen is ALREADY very HIGH in the body. However, very low concentration of a bacteria or virus (at a time when the symptoms of the disease are not yet visible) can be detected by AMPLIFICATION of their nucleic acid by PCR (Polymerase Chain REACTION). | |
| 20018. |
Question : Can a disease be detected before its symptoms appear? Explain the principle involved. |
| Answer» Solution :Yes, some diseases can be DIAGNOSED in their initial STAGES by using molecular PROBES, such as labelled DNA or RNA probes or ANTIBODIES. | |
| 20019. |
