DNA profiling

Cloning Background information: Cloning is a process where the DNA is replicated. It is done by having the DNA of an organism, human or animal, is put into an egg whose DNA is removed and when the egg is stimulated, the egg starts to duplicate. The results would be DNA is which genetically similar to the original organism. Cloning can also be applied to cells. The first mammal that was cloned successfully from an adult cell was the sheep named Dolly in the year 1996 by Scottish scientists in the…

Evolution is the change in the heritable traits and genetic codes of biological populations over successive generations which can give rise to biological diversity. Generally, evolution also define as the process which modern organisms have descended from ancient ancestors and the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth. The genetic differences that are heritable will passed on to their offspring or the…

Aim: This experiment will investigate the effects of different concentrations of fertilizer on the growth of duckweed. Hypothesis: It is expected that the cup with the most amount of fertilizer (cup D) over the 14 days will have the most amount of growth compared to cup A, B and C. Apparatus: 4x polystyrene cups 20x duckweed fronds (5 in each cup) 1x 5ml medicine teaspoon 1x tweezers 1x syringe 1x marker fertilizer Method: 1. Label each cup as A, B, C or D with the marker 2. Using the…

2. MONOCLONAL ANTIBODIES: 2.1. What are Monoclonal Antibodies? 2.1.1. “Clones” A clone is a group (family) of cells which come from a single parent cell that divides various times and are identical in all ways. In their structure, metabolic characteristics, functions, etc. 2.1.2. “Antibodies” An antibody is a protein which is produced by the human body’s immune system when it detects a substance that may be harmful (antigens like: bacteria, viruses, chemicals, parasites, etc). Antibodies…

alleged as A. hydrophila. Of 95 isolates were further screened using SNI 7303 (2009) methods which produce 56 isolates. The isolates were further screened using Dorsch et al. (1994) and Cascón et al. (1996) method. 3.2 Bacterial DNA isolation and Identification. DNA amplification using Dorsch method produced similar size amplicon to control sample A. hydrophila ATCC 7966. While Cascón method produces various amplicon sizes, some of them are similar to amplicon produced by control isolate.…

Heat stress is one of the major abiotic stresses affecting agriculture production worldwide which causes an array of physiological, biochemical and morphological changes in plants. Maize crop is unique among cereals on account of wider flexibility and adaptability in growing conditions, ranging from Kharif, Rabi and Spring seasons. Further, the response of plants to high temperature stress is reflected in apparent morphological traits like leaf firing, tassel blasting etc. The composite…

Critical Reaction #10: “Gattaca” Movie Summary In the not too distant future where genetic engineering in humans is common and DNA determines a person's social class. Vincent is conceived and born without the aid of this technology. Dealing with the nearly demolished physical dysfunctions of heart problems, as well as having a short life expectancy. The only way he can achieve his lifelong dream of going to space is to break the law and act as a "valid" person with appropriate genetic code.…

Age of puberty attainment in beef cattle is an important aspect for producers. This is because age at puberty is a key factor for a heifer’s lifetime reproductive performance. Beef cattle management programs aim for heifers to conceive by two years of age, but this can be a challenge when producing Bos indicus cattle. Puberty attainment in Bos indicus cattle is considerably lengthier than Bos taurus cattle, with the age at first calving typically being 40 months or more (Nogueira, 2003).…

Genetically modified food Nobody knows that how big the market of genetically modified foods will be in the future. Nobody knows that how serious the final effect of genetically modified foods will be. Nobody knows that how to deal with the damage for humans、animals and environment that caused by genetically modified foods. Despite all these, officials have long been aware of the problems in planting or eating genetically modified foods, according to news reports. In some cases, the most…

Cloning pets might not be the holy grail that everyone is hoping for. In 1996, scientists were celebrating the success in cloning their first mammal, Dolly the sheep. Recently, they found a way to clone monkeys using the same technique. Now, anyone willing to pay the price can get their beloved pet cloned. But cloning has some serious downsides. Cloning a pet can be very expensive and uses up hard-earned money. In addition, cloning a pet has countless of side effects and cloned animals have…
