You will be given a definition of a task first, then some input of the task.
Given a passage and a query based on the passage, generate an unambiguous, concise and simple answer to the query from information in the passage. Note that the answer may not be present in exact form.

Proteins are separated by charge in agarose because the pores of the gel are too large to sieve proteins. Gel electrophoresis can also be used for separation of nanoparticles. Gel electrophoresis uses a gel as an anticonvective medium and/or sieving medium during electrophoresis, the movement of a charged particle in an electrical field. What are the components of a gel electrophoresis chamber? What kinds of macromolecules can you look at with gel electrophoresis? Do you need to use different techniques for the different kinds of macromolecules? How do you visualize the macromolecules in the gel? What are real-life examples of what gel electrophoresis is used for? Bibliography Once these are separated, a photo is taken of the gel, providing a picture of the separated molecular parts. This process is called electrophoresis and helps us to better understand and identify the molecular components of living things. Forensics In the world of forensics, gel electrophoresis is used to obtain a DNA fingerprint of a criminal. This means that scientists can accurately tell whether two pieces of DNA, one found at a crime scene and one belonging to a suspect, are matches. Gel electrophoresis is a method for separation and analysis of macromolecules and their fragments, based on their size and charge. It is used in clinical chemistry to separate proteins by charge and/or size and in biochemistry and molecular biology to separate a mixed population of DNA and RNA fragments by length, to estimate the size of DNA and RNA fragments or to separate proteins by charge. Nucleic acid molecules are separated by applying an electric field to move the negatively charged molec Gel Electrophoresis and SDS-PAGE Gel Electrophoresis which includes Protein Gel Electrophoresis Current Uses of Gel Electrophoresis -Gel electrophoresis is a technique used for the separation of deoxyribonucleic acid (DNA), ribonucleic acid (RNA), or protein molecules by using an electric field and a gel matrix. DNA Gel electrophoresis is usually used in order for investigations. DNA profiling is the process of determining an individual's DNA characteristics, called a DNA profile, that is very likely to be different in unrelated individuals, thereby being as unique to individuals as are fingerprints. DNA profiling with the aim of identifying not an individual but a species is called DNA barcoding. DNA profiling is most commonly used as a forensic technique in criminal investigations to identify an unidentified person or whose identity needs to be confirmed, or to place a person at a crime scene or to eliminate a person from consideration. Electrophoresis is used in DNA for fingerprints for forensics, paternity testing, checking PCR reactions, disease detection and to look for evolutionary relationships among organisms. A solution of negatively charged DNA molecules are pulled through gel using an electric field. Thanks to TV shows like CSI, many people are familiar with the use of gel to separate macromolecules like DNA. However, gel electrophoresis91112 can also be used to separate out proteins. Different proteins have different sizes, mainly due to the number of building blocks in their structure. Gel Electrophoresis is used to separate DNA fragments by their sizes and charges. It makes it possible to identify the differences and similarities between different plants and animals. Although there are some different types of Gel Electrophoresis such as Capillary and Agarose, this is how the general technology works: Quick Answer. Electrophoresis, also called gel electrophoresis, is used to separate the macromolecules of DNA, RNA and proteins. DNA and RNA are separated according to their size and length, while proteins are separated according to their charges. Query: how is gel electrophoresis used in the field of forensics
Output:
In the world of forensics, gel electrophoresis is used to obtain a DNA fingerprint of a criminal.
