1. Gene technology refers to the manipulation of genetic material, including altering DNA in an organism to supress or enhance its activity, or combining genetic material from different species. Whilst biotechnology in the older times refers to how people use biological information to have effects on agricultural like crops and such. Not specific or in-dept. like manipulating genetic material.

3. A restriction enzyme is also known as restriction endonuclease, which is an enzyme that cus DNA at a particular sequence. In DNA technology, there have been 400 different restriction enzymes found and each specific sequence between 4-8. His will allow the scientist to stop any viruses or infection to enter the body through cutting the bacterial DNA.

6. A PCR is also known as Polymerase Chain reaction, and where this is a laboratory process which DNA polymerase is used to copy a sequence repeatedly, making millions of copies of the same piece of DNA.

9. In a hair piece, where the hair itself is made out of protein, it attachment to the skin, will have skin cells with DNA, but very limited number. To have a sufficient amount, they must
Restriction enzymes are a tool that allows us to pinpoint human identity down to single differences in our DNA. Work through the following simulation so you can see these molecular scissors in action.
1. If each individual has such a small amount of DNA, how do the bands on the gel contain enough DNA to be visible?
Restriction enzymes cut DNA at certain sites to create multiple DNA fragments. Restriction enzyme HindIII has known DNA fragment lengths and recognition sites when digesting lambda DNA, while the lambda DNA recognition site for restriction enzyme XhoI is unknown. The goal of this study is to determine the lambda recognition site of XhoI by comparing a HindIII digest and a HindIII and XhoI double digest on an electrophoresis gel. The HindIII digest had a band at 9.4 kb, but this band was not visible in the double digest, therefore we concluded the recognition site for XhoI was around 9.4kb. There were also two additional DNA
A restriction enzyme is an enzyme that acts as a catalyst that can cut a strand of DNA in a particular place.
1. Background/Introductions: Hormones are a regulatory substance produced in an organism and transported in blood to stimulate target cells or tissues into action. There are many glands and lobes in the endocrine system that produce hormones, but for this experiment we are particularly interested in the pituitary gland and the intermediate lobe because those are the two parts of it that produce Melanocyte Stimulating Hormone (MHS). These hormones are peptide hormones that are produced in response to UV light, but are not a direct feedback mechanism. When the hormones are secreted out of the glands, they travel through the bloodstream until they reach melanocytes located in the skin between the epidermal and dermal layers, where they transport
What does the PCR do? PCR is a method by which fragments of DNA can be duplicated. This makes PCR more sufficient amongst other Felds in forensic science.
Experiment 4 & 5: PCR did not work for my obtained DNA as there was no evidence of movement of the DNA. PCR did work for lab numbers 33 and 12. The size of my fragment could not be determined and cannot compare to the size that was expected. The negative control was clean as there was no traces of movements.
In a perfect world, what would everyone have? Well, they most likely would have good health, money, stability, and proper environment to live very productive lives. This is what people strive to have, but very few receive. Why? There are many reasons. One reason might be the lack of agricultural advancement in many countries. If these countries were to embrace genetically modified crops, the citizens would have much better lives. According to Osakabe, Yuriko, Kajita, and Osakabe, in their article “Genetic Engineering Of Woody Plants: Current And Future Targets In A Stressful Environment”, genetic engineering in plants is better than traditional breeding methods because “…they bypass the long generation for breeding…” (106).
2. Biotechnology means "the exploitation of biological processes for industrial and other purposes, especially the genetic manipulation of microorganisms for the production of antibiotics, hormones, etc." This basically gives off what Biotechnology is. In simpler terms Biotechnology studies living organisms and how it could b useful to us humans. The knowledge analyzed from the organisms allows researches and scientist to transfer genes between other cells and different organisms. The use of this is to help analyze these things to produce products that would be useful for the economy. There is two basic Biotechnologies and these are Traditional Biotechnology
The expression vector will be picked and cut, using the restriction enzyme Sma1. The cohesive ends will then be ligated with the blunt-ended cDNA. This process will be efficient with the inclusion of Oligonucleotide and T4 ligase (Croy, 2000) (4).
Altering the genome, or genetic makeup of an organism has traditionally been completed through a method called genetic engineering, or genetic modification, both are the same. Genetic engineering is usually completed by first identifying a specific gene in one species, extracting it from that species, and inserting it into another species, all on a cellular level. For example, imagine that there were two species of corn. One species of corn yields large bounties of corn, but has small kernels that are difficult to process. The second species has very large kernels but yields very little corn. For anyone selling corn, it seems obvious that if one could somehow combine the best qualities of each plant,
Enzymes are applied to DNA to break it into smaller pieces which are called restriction endonucleases. These restriction endonucleases become
The polymerase chain reaction or PCR for short can be used to create many copies of DNA. This allows the DNA to then be visualized using a dye like ethidium bromide after gel electrophoresis. The process has been refined over the years, however the basic steps are similar.
Advantages and Problems of Genetically Modified Agricultural Crops Genetically Modified food (GM) is most commonly used to refer to crop plants created for human or animal consumption, using the latest molecular biology techniques. These plants have been modified in the laboratory to enhance desired traits such as increased resistance to herbicides or improved nutritional content. Genetic engineering can create plants with the extract desired trait, both accurately and rapidly. For example frost can destroy sensitive seedlings, an antifreeze gene from cold water fish has been introduced to plants such as tobacco and potatoes, and with this anti freeze gene these plants are able to tolerate the
Among the millions of species that inhabit the planet, only twenty species provide ninety percent of the human food supply (Montgomery 2000). Since the introduction of genetic engineering, however, livestock and crops have a more productive future. Transfer of engineered genes from organism to organism occurs through hybridization, conjugation, and transformation in microorganisms. By the substitution of genes into agricultural species, biodiversity can flourish to improve social and economic development. Although methods of gene and DNA implantation quickly develop advanced products, even precise genetic alterations do not ensure that the environment will remain balanced or that changes in
