A genetically modified organism is any organism whose gene containing certain DNA has been modified using direct manipulation or biotechnology. This technology includes the changing of the genetic makeup of cells including the transfer of genes within and across species boundaries to produce an improved or novel organism. Genetic engineering can also be used to remove genetic material from a target organism. Genetic engineering techniques have been used in several fields including research,…

In 1963, the South African biologist Sydney Brenner proposed C. elegans as a model system for studies of development and neurobiology. Researchers share their findings in C. elegans genome via the internet with other researchers from around the world. The process of sharing the genome database on the world wide web provides a working framework for researchers who are working on the human genome project In 1969, John Sulston developed a technique to freeze and thaw the worm. As a result, the…

Association of Gene Polymorphisms and Development of Neurological Conditions Using Restriction Fragment Length Polymorphism Samir Nacer Lab Partners: Krystine Sora, Sierra Sandler, Ali, Alfredo Lam, Natalia Figueroa Biology 3600 Genetics I with Lab Instructor: Dr. Robert Smith Laboratory Assistant: Eileen Date of Experiment: November 7th, 2016 Abstract: A migraine is a neurological condition in which blood vessels dilate causing an extreme aching pain on a specific side of the human skull.…

One great organism to study is Caenorhabditis elegans (C.elegans ) because it is hermaphrodites, transparents and small enough to observe under the microscope. After adding mutagens to them, scientists can get all kinds of freak worms after few days. “Bag of worms” are one of them. It can not lay eggs so its body occupied with dozens of eggs. When eggs hatched inside the worm, larvae eat the mother worm and them come out. Ambros, a scientists who just finished doctor degree at MIT, first…

Discussion Alu is a transposable element that can be inserted into the human genome, enabling its use as genetic marker for ancestry differentiation,and thus identification. Due to new insertions, some humans do not have an alu insertions, while others may have accumulated mutations causing three types of polymorphisms, S1, S2 and L, the reference alu insertion, YB8 was useful as a standard to the comparison of nucleotide sequences changes to uncover the difference in the presence and absence of…

GMO is an organism in which the genetic material has been altered in a way that does not occur naturally. Scientist have been taking a piece of genetic material from one organism (plants or animals) and putting it in a chromosome of a animal. Genetically modifying animals have been around since the 1970’s. “Genetic engineering is able to create whole organisms that are not natural to the planet, and whose specific genetic make-up is as much a result of human manipulation as it is natural…

Significant quantities of DNA can be extracted from the coronal and root portions of tooth, including the root tips. However, the root body is the region that yields maximum quantitiy of DNA. The quality and quantity of DNA extracted from teeth provides a great advantage in forensic DNA analysis. [10] Teeth is divided into two parts anatomically: i) The crown - which is exposed in the mouth and ii) The roots which are enclosed in the alveolar bone of the jaws. Tooth roots which are composed…

This lab was very helpful because it taught several important procedures needed in many fields. Basically, this lab taught us the proper general protocol to use to obtain and grow the microorganisms we took from the inside of the human mouth. It taught us how to properly stain and mount the samples we grew. Of course it taught us how to view our stained specimen under a light microscope. Grow the microorganisms we obtained was the first part of the lab. What we used to culture our…

Genomic engineering is the process of modifying specific sites in DNA sequences of cells or organisms. The ability to achieve effective and precise editing of the genome has been achieved and advanced through the development of sequence-specific nucleases1. Zinc-finger nucleases and transcription activator-like effector nucleases (TALENs) are programmable DNA binding nucleases previously used to achieve this targeted editing of DNA. However these tools have been found to be both time consuming…
