are able to cleave DNA molecules at the positions at which particular short sequences of bases are present. The resulting digested DNA is very often selectively amplified using PCR‚ making it more suitable for analytical techniques such as agarose gel electrophoresis‚ andchromatography. It is used in genetic fingerprinting‚ and RFLP analysis. [1] Just as mentioned above‚ for this experiment we will be using restriction enzymes. Restriction enzymes or restriction endonuclease are enzymes isolated

using gel electrophoresis‚ and then estimating their fragment sizes. The size and number of fragments help to determine information about the structures of the original DNA pieces from which they were cut. To determine the size of an unknown DNA fragment that was inserted into a plasmid‚ gel electrophoresis is used. This technique is used in crime scene investigations. Gel electrophoresis separate charged molecules‚ including nucleic and amino acids‚ by how fast they migrate through the gel under

When western blotting‚ first the proteins are extracted and undergo Gel Electrophoresis‚ next it goes through elecroblotting‚ and finally detects the proteins. When the results after every step is completed‚ the membrane is analyzed based on where the bands are present in the gel. It has been told that actin and myosin is present in fish‚ making it tougher to chew in most cases. To test the theory of actin and myosin being

and a final procedure using gel electrophoresis. The Bacterial Transformation lab was performed to prepare the plasmid into a bacteria and to use that bacteria to amplify the plasmid in order to make large quantities of it. This is based on the natural function of a plasmid to transfer genetic information vital to the survival of the bacteria. The next process of DNA extraction involved the extraction of total genomic DNA‚ and extraction of bacterial plasmids.

Evaluation of gel A. pH: The pH of the various gel formulations was determined by using digital pH meter. B. Appearance: -The prepared gel bases were inspected visually for clarity‚ colour and presence of any particles. C. Homogeneity: All developed gels were tested for homogeneity by visual inspection after the gels have been set in the container. They were tested for their appearance and presence of any aggregates. D. Skin irritation test: Test for irritation was performed on human volunteers.

A Correction gel is a thin piece of polyester that has been dyed a specific color. When filming under fluorescent light correction gels can eliminate certain tints. Although the color correction gel for fluorescent light looks magenta it doesn’t actually add magenta to the light it simply removes the green. During the next part of this scene

Genetically Modified Organisms INTRODUCTION: The purpose of this lab was to identify if non-labeled food products are actually genetically modified foods. Before we could begin testing this theory we first had to gain an understanding about genetically modified organisms in general. This was rather easy because if you have been to any grocery store lately you have without a doubt seen products with labels saying "GMO-free" or even "contains only non-GMO ingredients." GMO actually stands for
