Another Post About Whats Happening in DNA
previousgeneticAs we discussed before in the previous article about personal genetic information, there is exciting news about the human genome and how the cost of a full genomic sequence is coming down rapidly.
Presently, there are more than 1000 DNA genetic tests that are available from testing laboratories. DNA genetic sequening are used for several reasons for example, pre-implantation genetic diagnosis, prenatal diagnostic testing, newborn screening, presymptomatic testing.
Also, for predicting adult disorders such as Huntington’s disease , presymptomatic testing for estimating the risk of developing adult-onset cancers and Alzheimer’s disease, conformational diagnosis of a symptomatic individual and forensic or identity testing.
There are many legal, social and ethical issues involved in DNA tests. The information from DNA genetic testing can affect the life of the individuals as well as their families. So information should be private and confidential. DNA Genetic testing is a complex process.
Preciously the costs for a full genomic DNA sequence one would pay many thousands of dollars. Now with the Ion Torrent company announcement that you can read the full article on DNA News. This is a website, http://DNAnews.org/ that you are going to want to bookmark and check often.
Next Generation Sequencing (1 of 2) – How to Sequence
Allen Van Deynze, University of California Davis, walks you though the latest in gene sequencing technology. The talk was delivered live at the Tomato Disease Workshop 2010 in Florida, USA, and sponsored by the NIFA funded SolCAP project.
By all means checkout wikipedia on genomics also.

Checking in to DNA Tests for Personal Genetic Information
containedDNA or deoxyribonucleic acid is a long molecule that is contained within almost all of our cells within the nucleus. The information in your DNA gets stored in the form of a code, which comprises of four nucleotide bases namely adenine (A), guanine (G), cytosine (C), and thymine (T). DNA is prearranged into extended structures named chromosomes, which are then duplicated previous to the division of cells.

Human beings contain 46 DNA molecules. Genes are working subunits of DNA. The genes take the instructions required for making thousands of proteins, which are available in a cell. All the proteins help to evaluate what your cell will finally look like, and also the kinds of jobs it will do.
DNA Genetic testing has radically improved lives of people. Some tests are then used for clarifying the diagnosis. These tests are also helpful for the physician to understand appropriate treatments. There are many other tests that permit families to keep away from having children, and also avoid devastating diseases. It also identifies people that are at high risk and can be prevented.
Currently, more than 1000 genetic tests are available from testing laboratories. DNA tests for personal genetic information are used for several reasons for example, pre-implantation genetic diagnosis, prenatal diagnostic testing, newborn screening, presymptomatic testing for predicting adult disorders such as Huntington’s disease , presymptomatic testing for estimating the risk of developing adult-onset cancers and Alzheimer’s disease, conformational diagnosis of a symptomatic individual and forensic or identity testing.
There are many legal, social and ethical issues involved in DNA testing. The information from this type of a test can affect the life of the individuals as well as their families. So information should be private and confidential.
Testing genetics is a complex process. There are many different DNA testing centers and we can recommend the following sites for more information: For DNA Testing Kits we use http://DNAKits.org, and for Genealogy DNA Testing we found a lot of great information at www.Genealogy.DNA.com.
