DNA is so long. 6 feet long DNA thread is exist in one human cell. If collects all DNAs which are existed in human cells then the length of all DNAs will be 11 billion kilometer that is more than 70 times the distance of Earth and the Sun. If a type writer wants to write the DNA then it can write complete DNA of one human cell within 15 years? 280 books will contain one DNA’s information. All the resources are not enough to write the information about the all cells.
