What is gene?
Gene is a blueprint of a human.
Your genes are the footprint of who you are. Humans are known to have approximately 26,000 genes. Each gene is made up of a special protein material called DNA（Deoxyribo Nucleic Acid), which translates genetic information necessary to sustain function and life. DNA is comprised of 4 amino acids/base letters; Adenine (A), Thymine (T), Guanine (G) and Cytosine( C) in sequential order. We inherit the DNA codes, or sequence, from both our parents, thus, this is why we resemble them.
What is the fifference between gene and DNA?
If gene is the "footprint", then DNA is the "paper and ink".
Gene, the footprint of life, is the paper that ink is written on. DNA, therefore, is the ink or the unique handwriting of each person.
What can I learn from genetic test?
Genetic Researchers have started to identify which genes affect the onset of lifestyle diseases.
Thus, a Genetic Test will allow you to understand which diseases you are at genetic risk of developing in the future. Of the Genes that are already mapped, it is known that each individual has a 0.1% difference in the sequence. Since the genes do not change during one’s lifetime, you need to only test once. You can make better lifestyle choices based on your risk profile.
