applied to the gel. The chamber is designed with a positive electrode (anode) at one end and a negative electrode (cathode) at the other end. Molecules with a net negative charge migrate toward the positive electrode and molecules with a net positive charge migrate toward the negative electrode because opposite charges attract. The overall charge of a molecule affects the speed at which it travels through the gel. Highly charged molecules migrate more quickly through the gel than weakly charged

In Lab 8‚ we had analyzed remains found at a wooded area near Jonesburg and tried to determine if the bones belonged to a 28-year-old woman who had been reported missing from a city within the vicinity. Upon analysis‚ it was determined that they did belong to a female. However‚ it was not possible to determine if the bones did belong to the missing women. Lab 12 presented the opportunity to genetically analyze the remains found. DNA profiling‚ also referred to as typing and fingerprinting‚ uses genetic

Lambda DNA Amplification by Polymerase Chain Reaction (PCR) Introduction/ Background* Since its introduction in 1985‚ polymerase chain reaction (PCR) has become a powerful tool in molecular genetic analysis. Today‚ it is used for applications such as cloning‚ analysis of DNA from ancient specimens‚ and analysis of human DNA for forensic applications. PCR is a test-tube DNA replication system for making many‚ many copies of‚ or amplifying‚ a defined segment of DNA. Using PCR‚ a selected target

PETERSON/AP BIOLOGY The diagram below shows a segment of DNA with a total length of 4‚900 base pairs. The arrows indicate reaction sites for two restriction enzymes (enzyme X and enzyme Y). (A) Explain how the principles of gel electrophoresis allow for the separation of DNA fragments. (B) Describe the results you would expect from electrophoretic separation of fragments from the following treatments of the DNA segment above. Assume that the digestion occurred under appropriate

| ABSTRACT This experiment will study the manner in which restriction enzymes cleave DNA as a result of being able to identify specific molecules of DNA strands (Wiki 2008). Electrophoresis will help identify the cleavage sites so that they can be mapped and their respective distances from one another determined. INTRODUCTION Restriction enzymes are produced by bacteria and they are responsible for protecting DNA. They accomplish

DNA sequencing From Wikipedia‚ the free encyclopedia [pic] The term DNA sequencing refers to sequencing methods for determining the order of the nucleotide bases—adenine‚ guanine‚ cytosine‚ and thymine—in a molecule of DNA. Knowledge of DNA sequences has become indispensable for basic biological research‚ other research branches utilizing DNA sequencing‚ and in numerous applied fields such as diagnostic‚ biotechnology‚ forensic biology and biologicalsystematics.

2.3 Gel Electrophoreses After the PCR program completed‚ 2.7μL of 10X loading dye was transferred into each PCR tube. An electrophoresis gel chamber was completely immersed by 1X Tae buffer. Then‚ 10μL of DNA ladder was loaded in to the middle of the gel‚ and 20μL of each PCR sample were loaded into distinguish location in the gel. After all lanes are loaded‚ electrophoresis was turned on at a constant rate of 110-115V for one hour. 2.4 Gel imaging and analysis After the gel electrophoresis
