WebBy comparing the size of DNA fragments produced by restriction digest, the “DNA fingerprint” of an individual can be generated. A DNA fingerprint would look similar to the gel seen in Figure 6. Figure 6: A DNA fingerprint would look similar to the gel seen here. Shorter fragments of DNA are closer to the bottom of the gel than longer fragments. WebGel electrophoresis is used to separate macromolecules like DNA, RNA and proteins. DNA fragments are separated according to their size. Proteins can be separated according to their size and their charge (different …

WebFeb 10, 2024 · Agarose gel electrophoresis is a form of electrophoresis used for the separation of nucleic acid (DNA or RNA) fragments based on their size. Negatively charged DNA/RNA migrates through the pores of an agarose gel towards the positively charged end of the gel when an electrical current is applied, with smaller fragments migrating faster.
WebDNA fragments travel faster through the gel matrix than longer fragments. Therefore, DNA electrophoresis results in separation of DNA fragments based on size [2].
