4 billion or more years ago, the first spec of life appeared as a bubble. This may not seem important, but this bubble wrote the chemical code for life, and then passed it on. This object that was passed on is DNA, which carries a person's individual traits. A DNA molecule consists of two strands that wrap around each other in the form of a double helix, whose sides, made of sugar and phosphate molecules, are connected by nitrogen, containing bases. The Four different bases that are present in DNA are adenine, thymine, cytosine, and guanine. The particular order of these base pairs is called the DNA sequence which specifies the exact genetic instructions required to create a particular organism with its own unique traits. Every three base pairs that a person has makes up a gene, and it is said today that a human has approximately 30,000 genes. To many doctors, DNA is considered the personal diary of each person, containing everything that has to do with someone's life,!
             how they will live their lives, what will go on in a person's life, and how they will die. One problem has presented itself though, the human genome contains roughly 3 billion base pairs. When scientists tried to find base pairs, it roughly looked like this || | | || and a scientist had to write the base pair on the side. To go through and record this much DNA would take forever, so something had to be done. So, in 1990, a project called the Human Genome Project got underway. This project was said that it will take 15 years to complete. A genome is all of a living thing's genetic material. It is the entire set of hereditary instructions for building, running, and maintaining an organism, and passing life on to the next generation. A primary goal of the Human Genome Project is to make a series of descriptive diagrams maps of each human chromosome at increasingly finer resolutions. Mapping involves dividing the chromosomes into smaller fragments so it ca...
