What property of DNA causes it to migrate to the opposite pole of a electrophoresis apparatus?
DNA is negatively charged due to its phosphate backbone. When an electric field is applied during electrophoresis, the negatively charged DNA molecules migrate towards the positive electrode (anode). This movement allows for the separation of DNA fragments based on size, with smaller fragments traveling faster and farther than larger ones.

What is a electrophoresis apparatus?
An electrophoresis apparatus is a laboratory device used to separate charged molecules, such as proteins or nucleic acids, based on their size and charge through an electric field. The apparatus typically consists of a gel matrix (like agarose or polyacrylamide), electrodes, and a power supply. When an electric current is applied, the molecules migrate through the gel, allowing for analysis and visualization of the separated components. This technique is widely used in molecular biology for applications such as DNA sequencing, protein analysis, and genetic fingerprinting.
Why do certain dyes migrate toward the cathode and others towards the anode?
Molecules migrate to different electrodes depending on the charge they carry. Positively charged dyes migrate toward the anode (the negative electrode) and negatively charged dyes migrate toward the cathode (the positive electrode)
What is the purpose of power supply in gel electrophoresis?
The power supply in gel electrophoresis is used to provide an electrical current that helps move charged molecules through the gel. By applying a voltage across the gel, DNA, RNA, or proteins migrate towards the opposite electrode based on their size and charge. This allows for the separation and analysis of molecules based on their molecular weight.
What is the Working principal of electrophoresis?
Separates DNA fragments so they can be seen
What fragments move the fastest in gel electrophoresis?
Smaller DNA fragments move faster in gel electrophoresis because they can more easily navigate the pores of the gel matrix, causing them to migrate quicker towards the positive electrode compared to larger fragments.
Which pieces of DNA will migrate to the bottom of the DNA gel first during electrophoresis?
During electrophoresis, smaller pieces of DNA will migrate to the bottom of the gel first.

Why do DNA pieces migrate from the top of the gel towards the bottom during gel electrophoresis?
During gel electrophoresis, DNA pieces migrate from the top of the gel towards the bottom because they are negatively charged and are attracted to the positive electrode at the bottom of the gel.
What is the principle of electrophoresis?
Electrophoresis is a technique used to separate charged molecules like DNA, RNA, or proteins based on their size and charge. It works by applying an electric field to a gel matrix, causing the molecules to migrate at different rates depending on their size and charge. This allows for the separation and analysis of biological molecules.
Why do certain dyes migrate toward the cathode and others towards the anode?
Molecules migrate to different electrodes depending on the charge they carry. Positively charged dyes migrate toward the anode (the negative electrode) and negatively charged dyes migrate toward the cathode (the positive electrode)
What is the opposite of migrate?
it is a movement of people and there is no opposite. Perhaps reside, or remain in situ could be used the opposite of immigrate is emigrate

This allows for the separation and analysis of molecules based on their molecular weight.
How would the reversal of polarity effect electrophoresis?
Electrophoresis is the motion of particles relative to some fluid influenced by an electric field. The voltage used will affect this electric field, and in turn affect the movement of particles.
What process uses electricity to seprate organic compounds?
The process that uses electricity to separate organic compounds is called electrophoresis. Electrophoresis involves applying an electric field to a solution containing the compounds, causing them to migrate at different speeds based on their charge and size, allowing for their separation.
What is used to sort DNA into different lenghts?
Gel Electrophoresis
What charge must the food dyes have had in order to move through the electrophoresis chamber?
In an electrophoresis chamber, food dyes must carry a net charge that allows them to migrate towards the electrode of opposite charge. Typically, if the chamber is set up with a positive electrode (anode) at one end and a negative electrode (cathode) at the other, the dyes must be negatively charged to move toward the positive electrode. Conversely, if the dyes are positively charged, they would migrate towards the negative electrode. The specific charge of the dyes can depend on the pH of the medium and the chemical properties of the dyes themselves.
