It is due to phosphate groups which are present in the backbone of the DNA's double helix. • The gel generally used for DNA is agarose gel which are obtained from seaweeds. • Treating ethidium bromide to the agarose gel makes it possible to see the separated DNA molecules because ethidium bromide easily binds to the DNA molecules. • The DNA ladder is a standard chart used to compare the bands obtained to easily identify the desired DNA.

[@corvinntoledo5008]

Toledo, Corvinn D. • Gel Electrophoresis is a laboratory technique used to separate and analyze DNA, RNA, or protein molecules based on their size and charge. • The technique involves placing the sample into a gel, which is then subjected to an electric field, causing the molecules to move through the gel based on their charge. • The gel acts as a molecular sieve, slowing down larger molecules and allowing smaller molecules to move through more quickly. • The separated molecules can then be visualized by staining the gel with a dye, such as ethidium bromide, which binds to the DNA and fluoresces under UV light. There are two main types of gel electrophoresis: agarose gel electrophoresis for separating DNA and RNA molecules, and polyacrylamide gel electrophoresis for separating proteins. • Gel Electrophoresis can be used for a variety of purposes, including DNA fingerprinting, genetic sequencing, and protein analysis. • The technique is widely used in molecular biology research and has many applications in fields such as forensics, medicine, and biotechnology. • Gel electrophoresis is a relatively simple and inexpensive technique, but requires careful attention to detail to achieve accurate and reproducible results

Hernandez, Martheena D. 8 - Chatelet * Gel Electrophoresis is important to Recombinant DNA Technology. It is the process of separating DNA fragments based on their size. * The term “Gel Electrophoresis” is derived from its process which is the movement of charged molecules over an electrical field happening on a GEL medium. * Agarose gel is the gel used in Gel Electrophoresis and is obtained from seaweeds. * After setting up, the first step is to create a “well-like structure” in the gel using a comb wherein the DNA samples will be placed. The well is placed on the side of the cathode (negative charged side) because DNA are negatively charged (because of the phosphate groups found in the backbone). * Furthermore, to track the DNA, colored loading dye is mixed with the samples. Note that the dye should travel faster when the electric current is turned on. * Once the dye reaches the other end (positive charged side), the electric supply is turned off. * To detect the separated DNA, it is mixed with Ethidium Bromide as this substance binds to the DNA molecules. Also, when exposed to UV light, bright orange colored bands are seen (these are the bands of DNA). * To give an idea of what DNA fragment to extract, a standard chart is used, DNA ladder. * Lastly, Elution is the process of cutting and extracting DNA fragments from the Agarose Gel. This process is used in downstream processing.

Martina Bianca Santamaria | Grade 8 - Del Mundo Gel Electrophoresis: - A method of separation or separation technique of DNA fragments by size with the use the of gel - In a gel medium, movements of charge molecules occur in an electric field. - Gel used in DNA is Agarose gel from seaweeds Principle of Separation of DNA Fragments: - Size of the parameter is used for the separation. The charge of a molecule helps with the mobility of the fragments but not all fragments move at the same phase. Smaller fragments are ahead of bigger fragments because of the constant size of the pores where the fragments will pass through Note: - In a DNA molecule, negative charge is present due to the phosphate groups. These are present in the backbone of DNA double helix impacts the negative charge. - The DNA molecules will move from negative cathode to the positive charge anode by the use of electric field with the help of buffer solution to conduct electricity better Process: - DNA dye is added to the DNA for us to be able to track the DNA because it is colorless, and it’s selective in such a way that it travels a bit faster than the DNA segment. Once the dye reaches the anode, then it’s the cue to turn off the power supply. After the Process: - We can't really see the separated DNA segment, unless the agarose gel would be treated with Ethidium Bromide and observed through ultraviolet light. Under the UV light we would see DNA Bands, and the separation by DNA fragments is successful. Analyzation: - To know the size of the DNA fragment, there’s a chart called “DNA Ladder." Once compared with chart, we can now easily identify the desired DNA fragment to be cut out and extracted. The cutting and Extraction of DNA fragments from Agarose gel is known as “Elution.”

Velasco, Mekaella 8 - Chatelet A technique called gel electrophoresis divides DNA fragments in a gel based on their sizes. Due to the fact that this method is performed in a gel medium and is based on the movement of charged molecules when exposed to an electrical field, it is known as gel electrophoresis. Gel, a comb, an electrical source, and a DNA sample with various-sized fragments are all required for the Gel Electrophoresis procedure. Near the negative terminal, the wells that load the DNA samples should be created. Using loading dye, we can observe how the DNA moves within the gel. To improve electrical conductivity, the buffer solution is used. Ethidium bromide and the agarose gel are used to observe the DNA molecules. To know the length of the fragments, we compare the bands obtained in standard chart or the "DNA laders".

(8- Edison) - Gel Electrophoresis is the separation of the DNA Fragments on a piece of gel. - It is a technique to separate the different DNA molecules based on their sizes since it is one of the most important process in recombinant DNA. - This separation technique is based on the charged molecules when exposed to electrical field and it occurs in a gel medium. - The charge of a DNA molecule is negatively charged due to the presence of phosphate groups. - The phosphate which is in negative charge and present in the backbone of the DNA double helix impart a negative charge to the molecule. - Agarose Gel is a gel generally used for DNA and It is obtained from sea weeds. - The pores that have small in size can be easily escape whereas the bigger size pores will be retained back. - The first requirement in order to work with Gel Electrophoresis is a complete set up including the casting tray, gel, comb, electrical supply and DNA sample. - To observe the separating segments of the DNA molecules, we treat the Agarose Gel with Ethidium Bromide which easily binds to the DNA molecules. - The larger molecules are the ones that moves slowly while the smaller molecules are the ones that moves fastly. - The DNA Ladder bands obtained are compared with a standard chart. - Elution is the process of cutting and extracting of DNA fragment from Agarose Gel. It is used for Downstream processing.

Aspiras, Mary Leana D. | 8-Avogadro - Gel Electrophoresis is the separation of DNA fragments based on their sizes with the use of Agarose gel which can be obtained from seaweeds. - It is known as "Gel Electrophoresis" since it is based on the movement of charged molecules in a gel medium when exposed to an electrical field. - DNA is negatively charged due to the presence of phosphate groups in the backbone of its double helix. - Due to the various size of fragments, smaller in size moves faster, and the larger ones find it difficult to move. - The gel used is a mesh-like structure and the pore size is almost constant. - Since DNA is negatively charged, the DNA fragments are loaded near the negatively charged electrode so they will move to the positively charged anode/electrode. - Colored loading dye is used to track the DNA since it is colorless. - The Agarose gel is treated with Ethidium Bromide solution to clearly see the bands of the DNA under UV light since Ethidium Bromide easily binds to the DNA molecules. - Any DNA band will be compared to a DNA ladder to know their sizes. - Once the desired DNA is identified, it will undergo a process called Elution, which is the cutting and extraction of a DNA fragment from the Agarose gel. - Gel Electrophoresis is considered one of the very important techniques in recombinant DNA technology.

Villarico, Jan Martin R. (8 - Edison) - Gel electrophoresis is a method that separates DNA or RNA based on it's sizes. - DNA is negatively charged because of Phosphate groups located in it's backbone. While Ethidium Bromide binds DNA molecules. - DNA samples move from the negative anode to the positive anode in the gel medium.

Shenna Osoteo 8 - Avogadro - Gel Electrophoresis is the separation of DNA Fragments on a Piece of Gel based on their sizes. It is called Gel Electrophoresis because of the movement of charged molecules present in Electrical Field - Agarose Gel are the common type of Gel that is used, and it can be found in Seaweeds. - Ethidium Bromide can be easily binds to the DNA Molecules - Elution is the process of cutting and extraction of DNA Fragments from Agarose Gel, and it is used for Downstream processing

Katrina ysabel G. Gubat (8-BOHR) Gel Electrophoresis - gel electrophoresis is a technique to separate the different DNA molecules based on their sizes - this separation technique is based on the movement of charged molecules when exposed to an electrical field and this movement occurs in a gel medium hence it's known as gel electrophoresis - the gel which is generally used for the DNA is agarose gel and it's obtained from the seaweeds - the gel that is prepared for the experiment here at the microscopic level we find that the gel appears to be a mesh-like structure and the pore size is nearly constant throughout - it's considered as one of the very important techniques used in recombinant DNA technology
