The correct Answer is:
To solve the question regarding what DNA fingerprinting relies on, we can break it down into the following steps: ### Step-by-Step Solution: 1. **Understanding DNA Fingerprinting**: - DNA fingerprinting is a technique used to identify individuals based on their unique DNA profiles. It is particularly useful in forensic science, paternity testing, and genetic research. 2. **Identifying Key Components**: - The technique relies on specific sequences of DNA that are unique to each individual. These sequences are often found in non-coding regions of the DNA, which do not contribute to the production of proteins. 3. **Role of Mini-Satellites**: - Alec Jeffreys, a British scientist, discovered that certain regions of DNA, known as mini-satellites, are highly variable among individuals. These regions consist of repeating sequences that can differ in length and number from one person to another. 4. **Non-Coding DNA**: - The non-coding regions, often referred to as "junk DNA," do not have a known function in coding for proteins. However, they contain variations that can be used to differentiate between individuals. 5. **Conclusion**: - Therefore, DNA fingerprinting relies on the differences in the patterns of these non-coding sequences (junk DNA) between individuals. This is the basis for identifying unique DNA profiles. ### Final Answer: DNA fingerprinting relies on the differences in junk DNA patterns between individuals.
