The vital components and techniques of gene cloning are as follows, the DNA sequence that contains the desired gene (EZH2) is amplified by Polymerase chain reaction. PCR was established by Kary Mullis in 1985, popularly known to amplify target sequences of DNA (EZH2) to a billion fold in several hours using thermophilic polymerases (Taq) ,primers and other cofactors (Sambrook and Russell, 2001). Three crucial steps are involved which are Denaturation (at 95°), Annealing of the forward and reverse primers (55-65°) and lastly primer extension (at 72°). After amplification the desired sequence is integrated into the circular vector (pbluescript) forming the recombinant molecule. For the compatibility of the insert and vector, both were digested with (EcoR1) so the same cohesive ends are generated in both, making it easier to ligate. EcoR1 is a restriction enzyme that belongs to the type II endonuclease class which cuts within dsDNA at its recognition site “GAATTC” (Clark 2010; Sambrook and Russell, 2001).

Each human being has something called DNA. DNA is described as genetics and an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms. DNA constructs of two nucleotide strands coiled around each other in a ladder like arrangement with the sidepieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine and pyrimidine bases adenine, guanine, cytosine, and thymine. Each chromosome consist of one continuous thread-like molecule of DNA coiled tightly around proteins and contains a portion of the 6,400,000,000 basepairs that make up your DNA.

Each chromosome is labeled as one of four types: A, C, G and T. Genomic medicine is the study of the sequence of those letters. Small changes in the code can make someone more susceptible to cancer and other diseases. The code letters can also differentiate one type of cancer from another. Understanding the genome can help doctor devise a better treatment regimen for any given patient. Professor Dame Sally Davies of the NHS is recommending that medical facilities rapidly sequence the genome for all patients. The NHS has already sequenced the generic blueprint of more than 31,000 patients. [2]

Cloning has the potential to bring desired changes in the genetic makeup of the individual. Through cloning, the genetic nature of both can be promoted while the negative properties can be eliminated. Cloning can also be applied to the plants to

The study of the hereditary information present in the genes of an organism is known as Genomics. Genomic research influences health care practice, and helps improve human health. There

The primary purpose is to identify a genetic marker or study the function of a specific gene. There are three steps involved in this process which are as follows: denaturation, annealing and elongation. Denaturation involves heating the DNA to agitate the hydrogen bonds, and annealing allows the temperature to be lowered so that the primers can be “annealed” to the single-stranded DNA template. The last step requires DNA polymerase to synthesize a new strand of DNA that is complementary to the RNA strand in the 5’ to 3’ direction (Amplifying DNA: The Polymerase Chain Reaction, 2016). The forward and reverse primers are needed to start the replication process by providing the appropriate nucleotides to the new strand. On the contrary, sanger sequencing makes copies of a target DNA, and the the DNA strand that will be sequenced is separated into two strands, so they can be copied through chemically altered bases. The altered bases cause the process of copying to terminate each time a particular letter is added to the growing DNA chain, which happens to all four bases until the fragments are put together to reveal the original sequence of the original DNA. The aforementioned processes are thoroughly explained to give an overview of the steps involved in providing the end products of the experiment, so an individual can manually decipher

This assignment is aimed to enable me identify an unknown sequence that has been provided. I have thereby used the DNA database, journals on cell division and medical publications in undertaking this assignment. To identify the sequence, application of theories and practical modelling is necessary for this kind of work. The sequence to be analysed is essentially the nucleotides present in cells sample under examination. Since each of the four typical nucleotides are available, chain extension continues typically until, by chance, DNA polymerase embeds a dideoxy- nucleotide which is indicated as hued letters rather than the ordinary de-oxynucleotide demonstrated as vertical lines. In the event that the proportion of typical nucleotide to the dideoxy forms is sufficiently high, some DNA strands will succeed in including a few hundred nucleotides before insertion of the dideoxy form stops the methodology.

Genomics is going to have a bigger impact on our health than any single innovation of the 20th century. As a result, we will live longer lives, but our lives will also grow more complicated as we will manage more information, we will know more about human biology than ever.

Cloning has been one of the most widely discussed and controversial scientific topics in the past decade. Cloning has been applied in many fields including the creation of new breeds of plants and animals. However, the cloning of plants has been practiced for hundreds of years. Cloning can be done on a larger level in animals and has potential benefits. The general process of cloning is to take one cell from the parent making the offspring and parent genetically identical (Tsunoda and Kato, 158-161). In addition by making completely identical cells, we can apply different treatments to different clones to see if they react in different ways. The potential benefits of cloning out way the consequences of cloning. In this paper I will first elaborate on microorganisms. Then I will talk about plants, animal and human cloning, and the controversies in cloning.

The more detailed structure of DNA analysis is to determine the nucleotide sequence. Over the time various methods have been developed to obtain the nucleotide sequence of DNA, currently the most widely used methods include automated sequencing and enzymatic chain termination. During this Case Study I will explain what a genetic mutation is and the difference between inherited mutations versus point mutations, I will also describe how the technology explained in "Cracking Your Genetic Code" can be used to detect mutations and predict your health, lastly I will give my opinion on whether or not genetic mapping should be utilize to develop and personalize medical treatment while identifying the dangers in knowing our personal genome.

Restriction enzymes recognize repeated or double stranded sequences in the DNA, which are also known as palindromes (meaning that they read the same in opposite directions)

Maurice Wilkins deserves the most credit for the discovery of DNA’s structure because without his research, it could’ve been years before DNA’s structure was truly understood. This is due to the fact that Wilkins was the first person to ever produce a photograph of DNA. He did this by using X-Ray Crystallography. Now, many will say that Rosalind Franklin provided a clearer, better picture, known a Photograph 51, than Wilkins ever did which ultimately lead to the discovery of DNA’s structure. However, she worked off Wilkins idea of using X-Ray Crystallography and would therefore never have produced the picture of DNA without his work. Others will say that Watson and Crick are the rightful heirs to the title of discovering DNA’s structure. However,

One the location of the gene is determined, the gene is then cloned (design primers and PCR the gene, insert gene into a vector). Cloning of the gene will allow for future experiments in which the gene can be manipulated in vitro or in

Sir Alec Jeffreys’ 1984 discovery of DNA fingerprinting in England has revolutionized the criminal justice system by enabling legal entities to determine innocence or guilt of a suspect to a much higher level of accuracy(Butler). This discovery has also provided the ability to identify victims of natural disasters or catastrophes like 911(Lippincott). Additionally, DNA testing or profiling, has helped doctors and researchers to identify medical conditions and illnesses, determine pre-existing conditions and prevent them sometimes before they actually occur(Roewer). Also, DNA could be separated from different individuals in mixed stains like, when two or
