DNA Gel Electrophoresis Analysis - Visualizing Genetic Fragments #117105 (License: Personal Use)

This grayscale image depicts an agarose gel used in molecular biology to separate DNA fragments by size. Lanes 1 and 2 contain discrete bands, lane 3 shows a concentrated smear indicating degraded or PCR-amplified product, and lane 4 includes two sharp bands likely representing purified fragments. A DNA ladder runs vertically on the left for size estimation.

Used in academic labs, research publications, and biotechnology training materials to illustrate nucleic acid analysis; matches user intent for learning gel interpretation, troubleshooting PCR, or documenting experimental results.
