What type of hybrid is formed in the hybrid capture technique?

• A. RNA:RNA hybrid
• B. DNA:DNA hybrid
• C. DNA:RNA hybrid
• D. Protein:DNA hybrid

Answer: (C)

In the hybrid capture technique, a DNA:RNA hybrid is formed. This technique is primarily utilized for detecting specific RNA sequences, often in the context of viral RNA or messenger RNA (mRNA) in various diagnostic applications. The process involves the hybridization of a DNA probe to the target RNA. During hybrid capture, the DNA probe is typically specific to the RNA of interest. Once the hybridization occurs, the DNA:RNA complex can be separated and isolated. This is significant because it allows for the detection and quantification of RNA molecules in a sample, providing insights into gene expression and the presence of viral infections. The selection of DNA as the probe in this hybridization is crucial, as it is stable and can be easily manipulated for detection purposes, such as through amplification strategies. This distinguishes the hybrid capture technique from other methods that may involve different nucleic acid pairings or hybridizations.
