DNA is the basis of life, literally. It is the building block of all living things. It is the blueprint of every living thing and accurately records the genetic makeup of living things at each step in the development of the species. DNA is a highly specific sequence of DNA building and is used to create the genetic code of living organisms. The DNA blueprint is passed down from generation to generation and accurately determines the characteristics of living things. It provides both the directions to reproduce DNA, and the exact way to do so.

As DNA was discovered, many questions were raised about its structure. People were not sure if it was simply a random chemical construct or if it really had any structure at all. Then, in the 1940s, after the world wars, research showed that the Y DNA had some structure. This enabled scientists to use the color coding technique to determine the relationship between DNA and the living things it impacts.
The modern version of the DNA color code is known as the four-color method. The four colors are red, orange, yellow, and green. They are based on the primary colors of the cells. The most commonly used color coding method is known as the Cybershot method. It is based on the principal of hues that the DNA contains.

The first step is to determine which type of DNA a cell contains. This is done by taking a group of cells and dividing them with a microscope. The dividing cells give a DNA sample. Samples can be collected from many locations and can be studied under a microscope or from a variety of lighting.
Next, cells are screened for non-homogenous groups. The screening is done using gel electrophoresis. When a test sample is found to contain this uneven distribution of cells, it is classified as a homogenous cell. This technique is more commonly used for counting and sorting the number of chromosomes in humans and other species.

After the cells have been sorted, they are treated with oxidizing agents. This oxidizing treatment produces red color. If the cells adhere to the screen, they are considered “colored” and their individual bases are identified. There are many variations of this method. The most commonly used variation is referred to as the gel electrophoresis-based method.
After the bases are identified, sequences of bases are extracted from the samples using methods such as PCR and sequencing. Then, the sequences are put together using polymerase chain reactions (PCRs). This sequence assembling is what creates the DNA blueprint of the organism. This DNA is essential for the building of life. It is important that the DNA be regulated and kept in check for various factors such as mutational stability, transcription factors, and the like.

This DNA testing has revolutionized the biological field. With the advent of molecular biology and DNA manipulation, there are now countless ways to analyze DNA. The methods available are highly effective and reliable. And now that DNA has been proven capable of affecting human and animal health, we can safely say that DNA is indeed red.
One of the most common methods of examining DNA involves fluorescent microscopy. Using an optical fiber, a beam of fluorescent dye is directed at the sample. The resulting images are then recorded and used to determine the location of the molecule or DNA. Another common method for DNA testing uses PCR (polymerase chain reaction) to transform DNA into a specific DNA structure. This DNA structure is then inserted into a DNA lab machine that generates the necessary replicated molecules. The desired result is then yielded.

Another method of examining DNA involves using bead separation. Using a sensitive technique known as electrophoresis, DNA is exposed to varying levels of salt solutions. As the solution becomes saturated with DNA, a color will appear. This method has shown excellent results when used on DNA samples from living organisms. It has also proven useful for many applications in biotechnology, such as genetic engineering, bacteria and virus cloning, and DNA fingerprinting.
The final method we will discuss involves the use of a technique known as X-ray fluorescence. This method utilizes the power of powerful X-rays to illuminate regions of the sample where the sample has been frozen. Because of this power, it has become an incredibly valuable method for both research and in the clinical setting.
