Restriction enzymes (endonucleases): proteins isolated from bacteria that cut nucleotides at specifi c sequences. RFLP: a process using a restriction enzyme to digest a DNA sample at specifi c sites to create a DNA profi le. Short tandem repeat (STR): short DNA sequences that are repeated numerous times within an individual’s chromosomes.

What is Restriction Enzyme? Definition, Role, Nomenclature ...

This and salt concentration also affect enzymatic structures. As a result, enzymes denature at extremes of pH and high salt concentrations. In addition, substrates and/or the enzyme's active site groups may become ionized. This further affects the enzyme-substrate binding. Again the pH at which an enzyme works best is called its optimal pH.

Enzymes, which are produced naturally by bacteria, cut DNA molecules at specific sites denoted by base sequences When a restriction enzyme is used to cut different DNA molecules, the size of the fragments generated will be unique to each molecule. As shown in Figure 1, both DNA 1 and DNA 2 are cut with HaeIII, an enzyme that

Lab 6B – DNA Fingerprinting Introduction: Restriction enzymes are endonucleases that actually cut the phosphodiester bonds on the sides of deoxyribonucleic acid. These endonucleases recognize specific DNA sequences in double-stranded DNA, which is usually a four to six base pair sequence of nucleotides. The endonucleases then digest the DNA at these sites.

Lab Report 5: Electrophoresis

The DNA restriction analysis experiment demonstrates that DNA can be precisely manipulated and that it behaves as predicted by the Watson-Crick structure. Students use restriction enzymes, the scissors of molecular biologists, to cut DNA from the bacteriophage lambda. The resulting DNA fragments are analyzed by agarose gel electrophoresis.

If you need to cut your DNA with two enzymes each requiring different digest conditions, you can.. A) Perform enzyme reactions sequentially, purifying the DNA before using it in the second reaction. B) Add more ligase to stabilize the digests between reactions. C) Perform the enzyme reactions sequentially, adding more DNA after the first reaction.

Big Genetics and Information Transfer 3

Each set of four restriction enzymes used in any one year contains two enzymes that cut the plasmid once and two that cut either two or three times. One of the single cutting enzymes is arbitrarily placed at base pair zero of the plasmid, and students are told to map other restriction sites relative to that enzyme site.
