An Examination of the Genetic Risk Factors in Drug Addiction

Drug Addiction: Are Genes to Blame? Drug addiction is a widely misunderstood condition. The timeless nature versus nurture debate is often brought up when discussing drug dependence. Is addiction a mental illness or a consequence of poor lifestyle choices? Are some people more susceptible to becoming addicts than others? The answers to these questions boils down to the analysis of genes and whether their roles influence drug addiction. Research from the National Institute on Drug Abuse in 2013 shows that most drug addictions begin under eighteen years of age, and drug use is highest among those in their late teens or early twenties. As a young adult, these statistics are frightening. Understanding more about the science behind addiction can help researchers and healthca...

The organism’s genetic makeup Essay Sample

The organism’s genetic makeup Essay Sample I chose a subject that is nasty in my opinion, but, I am choosing the scarlet king snake as my subject on natural selection. Decades have gone by since the extinction of the coral snake in parts of the southeast. In its place the scarlet king snake has taken over. “Batesian mimicry, in particular, is when a toxic species is mimicked by a more palatable one to deceive predators, conferring some survival advantage. The most precise mimics are favored by natural selection when their model becomes increasingly rare” CITATION Fan14 l 1033 (Fang, 2014). Though they look very much like their poisonous ancestors, the scarlet king snake is a non-poisonous snake. I guess if you like snakes they are kind of pretty in their bright red

Genetic Engineering Essay Sample

Genetic Engineering Essay Sample A) SELECTIVE (ARTIFICIAL BREEDING) Definition: Selective breeding is when the plants/animals from the existing stock that have the characteristics they want are selected and are allowed to breed. The offspring will hopefully display the characteristics which are required. The best offspring are then bred from, until all offspring display the characteristics that are wanted. This leads to new breeds of animal being produced. Uses: * High yielding crops, such as wheat are produced by collecting the seeds from only the plants that have a good yield of wheat. * Disease resistant crops can be developed. * Animals on farms are bred so that they produce more food, e.g. cows with better meat, hens that lay more eggs. * Animals such as dogs

Mitochondrial genetic disorders: monogenic disease

A monogenic disease is a condition determined by the interaction of a single pair of genes. Compared to the other, polygenic condition wherein several genes (polygene) are involved. The monogenic disease is less common than the polygenic disease. It is also less complicated than the latter and may follow a pattern based on Mendelian inheritance. They are inherited according to Mendel’s Laws (Mendelian disorders). The mutation can be spontaneous and where there is no previous family history. Inheritance patterns can be autosomal dominant, autosomal recessive or X-linked recessive. Over 10,000 human disorders are caused by a change, known as a mutation, in a single gene. Since monogenic disease involves a single pair of genes the dysfunctional or mutated gene may be ide...

Genetic Counseling Decision-Making

Genetic Counseling Decision-Making Essay Sample In my opinion, I think that Jenny and Bob Miller should take the necessary risks in order to make their sons life more comfortable and possibly cure them of their disease in the near future due to gene therapy. The gene therapy is not far from being a reality in medicine that can cure muscular dystrophy, and the injections of normal muscle cells from healthy individuals can relieve some of the pain they are experiencing until a cure is generated. Muscular dystrophy is a very painful disease and anything and everything should be done to help the individuals who suffer from this disease. Jenny and Bob Miller are a wealthy couple and have enough money to afford the injections for their children. Immunological rejection i

Genetic Disorder Report: Clinical Depression

A mutation is the changing of a gene’s structure, resulting in a various form that may be passed down throughout generations, that is caused by the alteration of single base units in DNA, or the deletion, insertion, or substitution of larger sections of the genes or chromosomes. Insertions are extra base pairs that are added, deletions are base pairs that are removed from the DNA, substitution is when a base pair exchanges one base for another. A type of genetic disorder is called clinical depression. Depression is known as a genetic, mental, and mood disorder that causes a constant feeling of extreme sadness and loss of interest in what a person used to consider fun. Depression is a disorder that ranges from mild to severe. Clinical depression, which is also known a...

Pre-Implantation Genetic Diagnosis essay

To detect any forms of genetic shortcomings in an embryo (formed during the process of vitro fertilization prior to pregnancy), pre-implantation genetic testing is performed. Pre-implantation genetic diagnosis (PGD) refers to a situation where one or both hereditary parents have an identified genetic deformity and analysis is carried out on an embryo to establish if it also bears a genetic defect. On the contrary, pre-implantation genetic screening (PGS) indicates the methods where embryos from recognized chromosomally ordinary hereditary parents are tested for aneuploidy (Catton, 2005).In several cases, as in the example case study, the PGD’s accuracy of detecting genetic defects may be way beyond 98%. Therefore once the doctor in charge receives the required genetic information, he/...

Genetic Fingerprinting in Paternal Testing essay

Paternity testing determines whether a person is the biological father of a particular child. The paternity testing procedure presupposes collection and examination the DNA sample of blood, skin, hair or anything else from a child and the father (who may be only alleged). Nowadays paternity tests are performed with the help of molecular genetic analyses.DNA fingerprinting is the test that aims to identify and evaluate the particular genetic information which is in a person’ s cells. They need only the small sample of cells as the reason behind a hair, blood, saliva, sperm, or sweat. DNA fingerprint scanning service remains the same in the course of th whole life regarding a person. Our cells contain a mix of 23 chromosomes from the mother in addition to 23 chromosomes through the dad....

Genetic Therapy essay

Introduction Gene therapy is among the most scrutinized medical applications. Genetic therapy characterizes the introduction of genes with the ability to prevent a disease from progressing and preferably to cure the disease.  A normally functioning gene is introduced into a cell where there are genetic anomalies or defects. In light of this, individuals, tissues or cells which have been subjected to genetic manipulation or modification are categorically transgenic. The purpose of genetic therapy is significantly the elimination of cancerous cells and pathogens, correct genes, which are defective, prevention of cardiovascular diseases and neurological disorders. Types of Genetic TherapyThe application of innate therapy is characterized directly into germ-line or somatic gene therapy (L...

Genetic Fingerprinting in Paternal Testing Issue essay

Questions of paternity presented a challenge to potential parents and researchers for many years. ABO phenotypes were used during the first half of the 20th century, the problem was that the blood group information of ABO only excluded potential paternity, but not confirmed the paternal relationship. Over the next few decades, the effectiveness of paternity testing was increased by additional blood markers, such as MN antigens, Rh antigens, and HLAs. But there was still room for errors. Sequencing techniques a DNA analysis presented a new look at people's genomes in the 1980s and 1990s.Parental testing is regarded to be genetic fingerprint scanning service which aims to determine a parent and a new child have any partnership, or other family relationships. The test gives innate proof ...
