Most genetic disorders result from defects in a single genes and many different procedures for examining genetic material have been developed.These procedures reveal an immense amount of knowledge about how changes in the genetic material can lead to various kinds of health issues. DNA tests, normally used in paternity tests determination can provide more information than about genetic compositions.

Chromosomes are made of one special molecule called DNA, which is the genetic material of which all genes are composed.

There are techniques that identify the chromosome on which the gene is located and how they work.

The order or specific sequences of the bases of the gene, provide the code for making a specific protein. Proteins are composed of amino acids, and each gene is responsible for producing a specific protein, which carry out the life supporting work of living organisms.

There are several types of proteins with different functions that are central in the activities necessary for life.

Lab techniques developed in recent years now make it possible to go beyond looking at whole chromosomes or measuring the proteins of specific genes and several types of tests can disclose details of the genes DNA.

No one has a perfect collection of genes, and we all have mutations in our DNA. Fortunately, change in DNA does not necessarily reflect a genetic disorder, which often depends on the location of the gene, and what task it directs, and how well the other genes are working.

The patterns of inheritance observed in families has long been studied, and it is now understood how diseases and other human traits can be passed through generations.

Tiny alterations or mutations that actually change the instructions contained in the DNA can be detected and mutations can be recognized.

Since DNA carries your life code, it is not far fetched to predict who, or what you will become in life by examining your DNA even before you are born, but despite our increased understanding of human genes and the growing constellation of genetic tests, the complex collaboration between the genes and the contribution of the environment still remains a mystery.

DNA testing has advanced to reduce the DNA tests cost and there are now very affordable costs test kits that can reproduce accurate results with DNA testing at home.

Despite the substantial influence that genes may have on our bodies, it is important realize that the effect that genes have on our health is influenced by the environment in which they function. Different mutations in the same gene can have different effects on health, and even the same mutation can affect different people differently. Some family members may be predisposed to cancer or heart disease that may develop with the presence of a particular gene, while other members with the same genetic makeup may be spared.

Nearly everyday, we may hear of dramatic discoveries from the field of genetics, but questions still remain about do we make effective use of DNA testing.

There are several types of DNA tests and serious legal and societal issues have been raised concerning the use and application of DNA testing results.

Advances in DNA testing may make it possible to design and alter life. DNA Testing can now be used for much more than paternity testing.
