Many people believe that it is common knowledge that HIV (human immunodeficiency virus) has no cure and will always be impossible to cure. However, contrary to these beliefs, someone has been cured of HIV-AIDS (human immunodeficiency virus-acquired immune deficiency syndrome). In 1995, Timothy Ray Brown had contracted and was tested positive for HIV-AIDS. Brown was able to lead a normal life until 2006 when he was told that he had leukemia. Gero Hutter, Timothy Brown’s oncologist, told Brown…

CRISPR Cas9 CRISPR Cas9 is a gene editing tool that can be used to edit, delete, and change parts of the genome. What makes CRISPR Cas9 different from other gene editing techniques such as Zinc Finger Nuclease (ZFN) or Transcription Activator-Like Effector Nucleases (TALEN) is its targeting efficiency ability. For example, ZFNs and TALENs could only reach targeting efficiencies from 1% to 50% in human cells. On the other hand, CRISPR Cas9 had a much higher rate at greater than 70% in Zebrafish…

use gene therapy as a treatment. Lab technicians isolate normal DNA and package it into a vector, which acts as a molecular delivery truck. These vectors are composed of viral DNA sequences. They either injected or given intravenously (by IV) into a specific tissue in the patient’s body. Thenceforth, the target cell (cell where a mutation occurred) is infected with the vector. After the infection takes place, the vector unloads its DNA cargo fostering the cell to produce proper proteins and…

In the world of engineering, the fairly new technology CRISPR lives up to its potential. CRISPR is a technology used to scan the patient 's genetic code and search for genetic diseases, it then “erases” the bad gene and replaces it with a neutral one. With this process we can eliminate many deadly genetic diseases such as Alzheimer 's, Diseases that causes the carrier to become blind, and some forms of cancer. Francisco Mojica discovered the gene editing tool in 1993. Although Mojica was the…

through the efferent arteries and to the rest of the body. Because a shark’s blood pressure is very low, they must be constantly moving to keep circulation going. Chromosomes are structures of protein and nucleic acids found in the nucleus that hold DNA in the form of genes, which are transferred from parent to offspring which determines the order of the monomers in a nucleic acid molecule. A haploid cell means that it only has half the chromosomes, so it’s from one parent, while a diploid…

more phosphate groups. Nucleosides are very similar, but do not have the phosphate group. 3. Deoxyribose is the sugar in DNA. Ribose is the sugar in RNA. The difference between the two is deoxyribose does not have sugar on the second carbon in the ring. 4. The 5’ end of the nucleotide has a phosphate attached to 5’ carbon. The 3’ end has a hydroxyl group on the 3’ carbon. C. DNA has the famous double helix shape with two polynucleotides wound around each other. The backbones run opposite to…

In 1972, American scientists Herbert Boyer and Stanley Cohen achieved the impossible; they inserted viral DNA into bacterial DNA. When this happened it was groundbreaking and soon led to the the ability for scientists to manipulate gene sequences in DNA. E. Coli was the bacteria that was first used to accept the plasmid known as pSC101 which was resistant to certain antibiotics (Genetics and Genomics Timeline). After repetition of this new process they decided to use the genes from the Xenopus…

structural DNA crystallizes to create organic life. With the others they state the same things that life can be created, just in all different ways. Primordial Soup Hypothesis, is the theory that long long before, life was created in oceans and lakes,…

A VNTR consists of a number of repeating DNA sequences, often a result of an uneven chromosome crossover or DNA replication slippage [6]. An individual’s VNTR loci exhibit considerable variation due to inheritance of alleles from each parent, and thus VNTR loci have been widely used for forensic fingerprinting and analysis [1]…

This allows the histidines to bind to the metal ion matrix filter while everything else in the mixture is eluted out (Bornhorst and Falke, 2010; Singh and Jain, 2013). To optimize IMAC, a DNA sequence coding for 6 histidines is most commonly used because it gives the highest affinity for the metal ions while not disturbing the function of the target proteins (Singh and Jain, 2013). The metal ions used in the filter are zinc, cobalt, nickel,…
