  이번 실험의 목적은 실험2에서 진행된 PCR product를 전기영동해 분리하고 분석하는 것이었습니다. 1000bp가 가장 이상적인 값이었지만, 8개 샘플 중 6개만 1000bp와 비슷한 곳에 나타났고 나머지 2개는 전혀 나타나지 않았습니다. 이는 2개 샘플의 DNA 농도가 상대적으로 낮아서 그런 것으로 보입니다. 또한 약간의 끌림 현상이 관찰되었는데, 이는 DNA가 깨졌거나 농도가 너무 높아서 생긴 것으로 보입니다. 이를 방지하기 위해서는 annealing 온도 조절, DNA 농도 낮추기, 겔에 거는 샘플의 양 줄이기 등의 방법을 사용할 수 있습니다.

  Agarose gel electrophoresis is a widely used technique in molecular biology and genetics for the separation and analysis of DNA, RNA, and protein molecules. This method relies on the principle that charged molecules will migrate through a porous agarose gel matrix when an electric field is applied, with the rate of migration being inversely proportional to the size of the molecules. The process of agarose gel electrophoresis involves several steps. First, the sample containing the molecules of interest is loaded into wells created in the agarose gel. An electric current is then applied, causing the charged molecules to move through the gel matrix. Smaller molecules will migrate faster than larger ones, resulting in the separation of the different components of the sample. One of the key advantages of agarose gel electrophoresis is its ability to provide a visual representation of the separation, allowing researchers to easily identify and quantify the different components of the sample. This technique is particularly useful in applications such as DNA fingerprinting, gene expression analysis, and the purification of specific DNA fragments for further study. Furthermore, agarose gel electrophoresis is a relatively simple and cost-effective method, making it accessible to a wide range of research laboratories and educational settings. The technique can be easily adapted to suit different experimental needs, such as the analysis of different types of biomolecules or the use of specialized staining methods to visualize the separated components. Overall, agarose gel electrophoresis remains an essential tool in the field of molecular biology, providing researchers with a powerful and versatile method for the separation and analysis of a wide range of biomolecules. As technology continues to advance, it is likely that this technique will continue to play a crucial role in the advancement of our understanding of biological systems and the development of new applications in fields such as biotechnology and medicine.
