gel electrophoresis

Explanation:

Gel electrophoresis is a technique used in molecular biology. It works by applying an electric field to a gel matrix (usually agarose or polyacrylamide). DNA fragments, which are negatively - charged, move through the gel towards the positive electrode. Smaller DNA fragments move faster and farther through the gel pores than larger ones. This results in a separation of DNA fragments based on their size, creating a readable pattern (bands) that can be visualized, for example, by staining the gel with ethidium bromide.

Genetic engineering is a broader field that involves manipulating an organism's genes. Biotechnology is a wide - ranging discipline that uses biological systems for various applications. Recombinant DNA is a product of combining DNA from different sources. Gene probes are short DNA or RNA sequences used to detect specific target sequences.
