Is the Human Race Evolving to Have Three Strands of DNA?

Many scientists are challenging the idea that we humans have more than two or even three strands of DNA. Some even believe that we may have a total of 12 strands or more. DNA is the acronym used for deoxyribonucleic acid. It contains the codes that act like a blueprint, giving instructions to cells and telling them how to behave. Most DNA is found in the cell nucleus (nuclear DNA), while a small amount is found in the mitochondria (mDNA).
The conventional DNA model is believed to carry the informational code made from four chemical bases. There are about 3 billion bases in the average human DNA and over 99 percent of DNA is the same in all people. This means that a very small portion, less than one percent of DNA, differs from person to person.
Most of us are aware of the two strands DNA model that is formed when nucleotides are arranged in two long strands, forming a spiral called a double helix. The structure of the double helix looks somewhat like a ladder. The way DNA is structured allows it to store more than 700 terabytes of information in a single gram of DNA. That is pretty amazing!
