DNA is life's hereditary material, i.e. it holds and passes on the genetic information from parents to offspring. The information carried by DNA directs the construction of each organism, its maintenance, proper functioning and reproduction. The information is carried in coded form as sequence of specific chemicals called nitrogenous bases. Just as a computer code is a unique sequence of 0s and 1s, so is life's genetic code a unique sequence of bases. There are about 2.5 metres of DNA in the nuclear DNA of each human cell. Therefore, we each have about 250 billion kilometres of DNA in our body. Every second we make enough DNA to encircle the equator 3 times. We make about 50 million new cells every second. so what's the secret of the DNA
