Gene isolation For GATE
A researcher wants to isolate a specific gene encoding for a protein involved in a particular disease. The gene is known to be present in a human genomic DNA library. Describe a method to isolate this gene using PCR (Polymerase Chain Reaction) and confirm its presence using Southern blotting.
Step 1: Designing Primers– The researcher designs two primers,forward primer (5′ → 3′) and reverse primer(3′ → 5′), that are complementary to the flanking regions of the target gene. These primers are specific to the gene of interest and do not bind to other regions of the genome.
Step 2: PCR Amplification– The researcher sets up a PCR reaction with the human genomic DNA library as the template, the designed primers,Taq polymerase, and dNTPs. The reaction is run through a series of temperature cycles to amplify the target gene.
- 94 Initial denaturation
- 60 Annealing
- 72 Extension
- Repeat for 30 cycles
| Temperature (°C) | Time (minutes) | Description |
Step 3: Southern Blotting– The amplified gene is then separated by agarose gel electrophoresis and transferred to a nylon membrane using Southern blotting. A probe, a labeled DNA fragment complementary to the target gene, is hybridized to the membrane. The presence of the target gene is confirmed by detecting the probe-gene hybrid.
The isolated gene can be further analyzed usingDNA sequencing to confirm its identity and expression analysis to study its role in the disease. This approach demonstrates the application of isolation of gene techniques, such as PCR and Southern blotting, to real-world problems in molecular biology.
