Human Genome Project and its Impact on Biochemistry: An Experiment
Experiment Title: Mapping a Single Gene Using Polymerase Chain Reaction (PCR) and Gel Electrophoresis
Materials:
- DNA sample containing the gene of interest
- PCR Master Mix containing DNA polymerase, nucleotides, and buffers
- Forward and reverse primers specific to the gene of interest
- Thermal cycler for PCR
- Agarose powder
- Tris-acetate-EDTA (TAE) buffer
- Gel electrophoresis apparatus
- DNA ladder
- Ethidium bromide
- UV transilluminator
Procedure:
- Prepare the PCR Reaction Mixture:
- In a PCR tube, combine the following components:
- 10 μL of PCR Master Mix
- 1 μL of each forward and reverse primer (10 μM stock concentration)
- 5 μL of DNA sample
- Nuclease-free water to make up the final volume to 20 μL
- Run the PCR Reaction:
- Program the thermal cycler with the following conditions:
- Initial denaturation: 95°C for 5 minutes
- 30-40 cycles of:
- Denaturation: 95°C for 30 seconds
- Annealing: 55-60°C (temperature specific to the primers) for 30 seconds
- Extension: 72°C for 1 minute per kilobase of expected amplicon size
- Final extension: 72°C for 5-10 minutes
- Prepare the Agarose Gel:
- Weigh out 1 gram of agarose powder.
- Dissolve the agarose in 100 mL of TAE buffer by heating in a microwave or on a hot plate until the agarose is completely dissolved.
- Allow the agarose gel to cool to approximately 50°C.
- Add ethidium bromide to the agarose gel at a concentration of 0.5 μg/mL.
- Pour the agarose gel into a gel electrophoresis apparatus and allow it to solidify.
- Load the PCR Product and DNA Ladder:
- Mix 5 μL of the PCR product with 1 μL of 6X loading dye.
- Load 10 μL of the PCR product mixture into one well of the agarose gel.
- Load 5 μL of a DNA ladder into a separate well of the agarose gel.
- Run the Gel Electrophoresis:
- Fill the gel electrophoresis apparatus with TAE buffer so that the gel is submerged.
- Connect the electrophoresis apparatus to a power supply and set the voltage to 100 volts.
- Run the gel electrophoresis for approximately 30-45 minutes, or until the DNA fragments have separated sufficiently.
- Visualize the DNA Fragments:
- After electrophoresis, transfer the gel to a UV transilluminator.
- Expose the gel to UV light and observe the DNA fragments. The DNA fragments will fluoresce under UV light due to the ethidium bromide.
- Compare the size of the PCR product with the DNA ladder to determine the approximate size of the amplified DNA fragment.
Significance: This experiment demonstrates the power of PCR and gel electrophoresis in mapping a specific gene within the human genome. By designing primers specific to the gene of interest, researchers can amplify the desired DNA sequence using PCR. The amplified DNA fragment can then be visualized on an agarose gel, allowing researchers to determine its size and location within the genome. This information is critical for understanding gene structure and function, diagnosing genetic diseases, and developing new therapies.
The Human Genome Project, which was completed in 2003, was a massive undertaking that involved sequencing the entire human genome. This project revolutionized the field of genetics and had a profound impact on biochemistry. The information obtained from the Human Genome Project has led to a deeper understanding of human health and disease, and has facilitated the development of new drugs and treatments.
This experiment provides a hands-on experience with PCR and gel electrophoresis, two techniques that are essential for modern biochemistry research. By completing this experiment, students will gain a deeper understanding of the Human Genome Project and its impact on biochemistry.
