DNA
DNA - THE LADDER OF LIFE
The word DNA stands for Deoxyribonucleic Acid. DNA is a complex molecule that contains all of the genetic information and biological information, which are necessary to build and maintain a living organism. Living creatures in Earth are all have DNA within their cells. DNA is the unique thing for every person. Therefore, it is used to identify between people. DNA also contains all types of instruction for making proteins that tell the cells what role it will play in your body.
DNA can be found inside the nucleus of every single cell, apart from red blood cells. It is tightly wound and spread throughout the 46 chromosomes. One set of 23 chromosomes is inherited from each parent. Inside the chromosomes the DNA exists as genes. A gene is a sequence of DNA. Genes carry codes for one protein.

James Dewey Watson (an American molecular biologist and geneticist) and Francis Crick ( a British biologist) are all best known as the discoverers of the structure of DNA in 1953. DNA has a unique three-dimensional shape. The DNA molecule comes in the form of twisted ladder shape, which scientists call a "double helix". At the most basic level, all DNA is composed of a series of smaller molecules called nucleotides. In turn, each nucleotide is made up of three primary components: a nitrogen-containing which is known as a base, a carbon-based sugar molecule called deoxyribose and a phosphorus-containing known as a phosphate group (PO4). There are four different DNA nucleotides (four chemical bases), each defined by a specific nitrogenous base: Adenine (abbreviated "A"), Thymine (abbreviated "T"), Guanine (abbreviated "G"), and Cytosine (abbreviated "C"). Double-stranded DNA consists of two polynucleotides that are arranged such that the nitrogenous bases within one polynucleotide are attached to the nitrogenous bases within another polynucleotide by way of special chemical bonds called Hydrogen bonds. This base-to-base bonding is not random, it joins together according to special rules (complementary base pairing). Each A in one strand always pairs with a T in the other strand, and each C in one strand always pairs with a G in the other strand.
Interesting Facts about DNA:
1. If you unwarp all of the DNA you have in all your cells, you could reach the moon 6000 times.
2. 99% of our DNA sequence is the same as other humans'. There is only 0.1% DNA difference between us may have to do with the number of nucleotides in a person's DNA.
3. It would take a person typing 60 words per minute, 8 hours a day, around 50 years to type the human genome.
4. You have 98% of your DNA in common with a chimpanzee.
5. DNA can store 25 gigabytes of information per inch and is the most efficient storage known to human. So, humans are better than computers.
