The Human Genome

Scientists are still away from identifying and characterizing the fibers in the body.  However strides are made to give a basis for C analysis.  This reaches to the source of life and ultimately this source of proteins.  This foundation is laid by splitting the entire genome sequence, or DNA (gene) sequence of an organism.  Starting with yeast , microscopic worms, and bacteria, computational biologists and scientists have enlarged DNA sequence information to include plants and certain animals.  DNA sequencing's ultimate aim is the human genome.  This sequence would allow the understanding of the foundation of human existence.  Many groups have come together to work in the Human Genome Project, to achieve this goal.

The sequencing of the human genome, which is finding the order of this more than 3 billion nucleotides (A, T, C, and G) from the human chromosomes, is being accomplished by two independent groups of scientists.  The two variants of this sequence were published in the magazines Nature and Science at February 2001.  One group is Celera Genomics, of Rockville, Maryland, a business launched in 1998.  The other research group is the result of a consortium of agencies with laboratories in several countries.

The string of the genome completed by the public market has a price of more than $3 billion.  The Significant sponsors were the U.S. Department of Energy and the National Institutes of Health (NIH), in Addition to the Wellcome Foundation of All England.  The present map covers about 95 percent of the human genome and has been proven to be 99.96 percent accurate.  This work has revealed, in an unexpected way, that the human genome has about 30,000 genes instead of 70,000 to 140,000, according to previous estimates.  Having a DNA chain of over 3 billion base pairs (bp) and also thinking about the normal gene size of 3,000 bp, then it is projected that only 3 percent of the human genome actually codes for some protein.  This means that about 97 percent of the human genome has no coding function; that is, most of the nucleotide sequences in human DNA don't code for genes.  This nonfunctional portion of DNA hasalso for lack of a more accurate term, been called "junk DNA," and its function and purpose have yet to be comprehended.  More significant, the data in the Human Genome Project has also revealed that each human being, independent of apparent gaps, is about 99.9 percent identical to any other individual.

With emphasis in the Human Genome Project and so much interest, what would be the applications of this sequence of the genome?  The information will aid in the identification of infection, an awareness of the predisposition to genetic disorders, and also in counseling.  For instance, the string of the genome enables geneticists to understand why individuals have a predisposition to heart disease, and it will cause the development of new medications designed to fight the reason behind disease and not the symptoms.  Sequencing the genome is likely to make basic scientific understanding to the development of gene treatments for diseases, like diabetes, muscular dystrophy, cystic fibrosis, Alzheimer's disease, and Parkinson's disease.

By the start of 2002, geneticists had already isolated around genes and also discovered about their purposes, including those that code that when mutated result in a predisposition for developing breast cancer as well as prostate cancer.  All this information is included in every single cell of the body.  It might reach seven feet if it had been possible to stretch out the quantity of information found in the DNA of the chromosomes in a single human cell.  If of the cells of the body's DNA were stretched out and aligned, it'd be enough to cover the distance from Earth.  Incredible packaging mechanisms enable this information to be kept within each cell that is tiny.

Concerns of This Sequencing Project
The significance of the Human Genome Project has raised concerns biological and ethical.  These concerns are being addressed as the information is being refined and utilized by people worldwide.

Confidentiality and protection of the information that is genetic: Who owns the information that is genetic?

Right to work with the genetic information by insurance companies, employers, courts, schools, adoption agencies, and so forth: that should have access to personal information that is genetic and how should it be utilized? Biotech recruiters have the challenge to find specialized scientists to fill needs in Boston, Seattle, LA, and San Francisco.

Psychological stigma and effect attached to an individual gapscan genetic information influence an individual and society's perception of that person?  Does information that is genomic influence members of minority communities?

Reproductive issues, including informed consent for procedures that are potentially contentious and complicated, use of genetic information in rights, and decision making: Do health-care personnel properly educate parents about the hazards and limitations of genetic technology?  How reliable and useful is genetic testing?  What are the issues raised by new reproductive technologies?

Clinical issues, for example, education of doctors and other health providers, patients, physicians and also the general public in genetic capabilities, scientific limitations, and societal risks, including implementation of standards and quality-control steps in examining processes: How will genetic tests be evaluated and regulated for accuracy, reliability, and utility?  (Currently, there is not much regulation at the federal level.)  How do we prepare professionals to the newest information?  How do we prepare the public?  How do we as a society balance societal risk with benefits and current limitations?

Uncertainties associated with genetic tests for susceptibilities and intricate conditions (e.g., heart infection) connected to multiple genes and environmental interactions: Should testing be performed when no treatment is currently available?  Should parents have the right to have children examined for ailments?  Are tests reliable and interpretable by the community?

Philosophical and conceptual implications about human responsibility, free will vs determinism that is genetic, and notions of illness and health: Why do people's genes make them behave in a given way?  Can folks control their behaviour?  What is considered acceptable diversity?  What is the line between therapy and improvement?

Health and environmental issues regarding genetically modified (GM) foods and microbes: Are GM foods as well as other goods safe to humans and the environment?  How will these technologies affect developing nations' reliance on the West?

Commercialization of products including real property rights (patents, copyrights, and trade secrets) and access of data and substances: Who owns genes and other parts of DNA?  Will the patenting of DNA sequences restrict their access and development into useful goods?

Incredible advancements have occurred in the last century.  Genetics has emerged from the findings of concerns and biology over the inheritance of traits from parents to offspring.  The science has since been enhanced to show the sequence of nucleotides.  This has helped scientists realize that the genetic code is universal, meaning that a nucleotide chain, from soybean, cattle, cattle, or microbes, will result in the production of the same protein with a function.  That is the foundation of biotechnology, allowing contractors to transfer genes among species, with the objective of transferring desired traits.  With a basic understanding of biology, an individual can start to learn biotechnology.

Advent of Biotechnology

Biotechnology is any technology.  In actuality, well before humans fully understood biology, they  worked in the production of bread and wine together with biotechnology.  Individuals manipulated micro organisms , plants, and animals' inborn properties to make goods for their use.  Together with the buildup of knowledge and increased experience with modern biological techniques, this definition has expanded to include a few applications from recombinant deoxyribonucleic acid (DNA) technology to tissue culture, in the production of services and products.  What distinguishes the procedures of modern biotechnology careers are not the fundamentals involved, however the techniques used.  As an example, traditional genetic improvements and molecular techniques share several factors, such as their objectives.  Both procedures try to come up with products that are more good for humans.  Technological improvement provides consequences than conventional progress in harvest variety.  Attribut

Obesity and gastroesophageal cancer risk

To systematically and quantitatively overview the connection of abdominal obesity, as measured by waist circumference (WC) and waist to hip ratio (WHR), to total gastro esophageal cancer, gastric cancer (GC), and esophageal cancer.  PubMed and Web of Science databases were searched for studies analyzing the association between abdominal obesity and gastro esophageal cancer (GC and/or esophageal cancer) upwards to August 20-16.  A random-effect model was used to calculate the summary relative risks (RRs) and 95\% confidence intervals (CIs).  Seven cohort studies -- one publication included two distinct cohorts -- from six publications were included in the recruitment.  An overall total of 2130 cancer cases diagnosed amongst 913182 participants.  Higher restroom and WHR were significantly related to increased chance of total gastro esophageal cancer (WC: RR 1.68, 95\% CI: 1.38, 2.04; WHR: RR 1.49, 95\% CI: 1.19, 1.88), GC (WC: RR 1.48, 95\% CI: 1.24, 1.78; WHR: 1.33, 95\% CI: 1.04, 1.70
