Final answer:
Potential sources of error in gel electrophoresis include spontaneous errors by DNA polymerase, exposure to gamma radiation, exposure to ultraviolet radiation, and exposure to intercalating agents.
Step-by-step explanation:
Potential sources of error in gel electrophoresis include:
- Spontaneous errors by DNA polymerase, which can lead to incorrect amplification of DNA fragments.
- Exposure to gamma radiation, which can damage the DNA fragments and affect their migration through the gel.
- Exposure to ultraviolet radiation, which can cause crosslinking of the DNA fragments and alter their mobility during electrophoresis.
- Exposure to intercalating agents, which can bind to the DNA and change its conformation, affecting its migration through the gel.
