Transcribed Image Text:**Transcription of Gel Electrophoresis Image for Educational Website**
**Description:**
This image presents an example gel electrophoresis analysis. The gel shows DNA from two crime scenes (CS1 and CS2) and DNA samples from two individuals (DNA1 and DNA2), each digested with two different restriction enzymes (Enz1 and Enz2). The lanes are labeled at the top to indicate which sample is present in each lane.
**Visual Elements:**
- **Lane Labels:**
- CS1, CS2: Crime scene samples.
- DNA1, DNA2: DNA samples from individuals.
- Enz1, Enz2: Different restriction enzymes used for digestion.
- **Gel Image:**
- Bands represent DNA fragments of different sizes.
- Crime scene samples and individual DNA samples are run side by side for comparison.
- **Annotations:**
- Blue and red dots above lanes indicate specific matches.
- "**Both similar to CS1**" above the DNA1 lanes, suggesting a match with CS1.
- "**DNA2 matches CS2**" above the DNA2 lanes, indicating alignment with CS2.
**Handwritten Notes:**
- "Which suspects DNA matches that found at the crime scene? Does this automatically mean the suspect is guilty?"
**Figure Text:**
- "Figure 7.2 Example gel image of suspect and crime scene samples. Samples were digested with restriction enzymes and run on a 0.8% gel..."
This gel electrophoresis is used to compare DNA samples against evidence collected from crime scenes to determine potential matches. Matching DNA bands suggest genetic similarity, crucial for forensic investigations. However, it is important to note that a DNA match does not automatically imply guilt, as additional context and evidence are necessary for legal conclusions.
