reads the same backwards and forwards. Gel electrophoresis is a method for separation and analysis of macromolecules (DNA‚ RNA and proteins) and their fragments‚ based on their size and charge. Nucleic acid molecules are separated by applying an electric field to move the negatively charged molecules through an agarose gel. Shorter molecules move faster and migrate farther than longer ones because shorter molecules migrate more easily through the pores of the gel. This phenomenon is called sieving.

METHODS The method used in this lab to map the proteins was the method of Polyacrylamide gel electrophoresis. This method can be used to separate the proteins present in the fish muscle and separates them on size. Due to the fact that they are separated by size‚ the proteins can be compared because similar proteins with stop at the same spot in the gel. So measuring the bands that show up on the gel you can determine if different fish species have similar proteins. The first thing that is

The Trees of Life In biology‚ there is a study of evolutionary relationships in groups of organisms where the relationship between the organisms is discovered through morphological data and molecular sequencing data; this is the study of phylogenetics. This is an important field of biology because these phylogenetic trees also grouped together individuals with similar traits in an organized fashion; which Charles Darwin created in his The Origin of Species book. The phylogenetic trees are

analyze what proteins and how much of the protein are in a gel. A western blot is very sensitive to proteins with histidine or HIS tags. Anything that contains histidine will show up in the gel. The western blot is evidence to whether or not if IL-8 is in the gel. The importances of the western blot is to show how well the proteins reacts to a disease. The first step for a western blot is to run an unstained PAGE gel. Western blot uses gel electrophoresis or electrical to arrange the proteins in order

Objective: DNA is analyzed by agarose gel electrophoresis after being digested with EcoRI restriction endonucleasse. Procedures: λ DNA and puC18 DNA were put into two tubes respectively. Then‚ EcoRI buffer‚ EcoRI enzyme and deionized water would be put into both tubes. EcoRI enzyme was the restriction enzyme that cut the DNA at the specific sequence. The EcoRI buffer enhanced the stability of many enzymes and binds contaminants that may be present in DNA preparations. DI water was used to

Purpose In this lab‚ we used PCR and gel electrophoresis to identify genetically modified food. Introduction A genetically modified organism is an organism whose DNA or genetic makeup has been modified to code for certain desirable traits("Genetically Modified Foods"). Common genetically modified plants include corn and soy‚ and common genetically modified animals are fish. Many genetically modified plants are coded to resist bugs‚ grow faster‚ and produce bigger fruit‚ while most GMO animals

and placed in the thermal cycle. Gel electrophoresis is being run in order to analyze and compare the DNA samples at the crime scene with the guilty suspects. Gel electrophoresis is used to separate DNA using an electric current applied to the gel matrix‚ which causes the DNA samples to move towards the positive charge. The results obtain from the gel electrophoresis able to concluded the which suspect have been at the crime scene by analyzing against the

However‚ after the second attempt‚ it was successful. The gel ran well‚ and the proteins from the gel were successfully transferred to the membrane provided in the kit. Introduction The name western blot was given to the technique by W. Neal Burnette and is a pun on the name Southern blot. Southern blot was a name given by
