Question
Why is the Human Genome Project called a mega project?
✓
Answer
Human Genome Project (HGP) is called a mega project. Human genome is said to have approximately 3x109 bp, and if the cost of sequencing required is US $ 3 per bp (the estimated cost in the beginning), the total estimated cost of the project would be approximately 9 billion US dollars. Further, if the obtained sequences were to be stored in typed form in books, and if each page of the book contained 1000 letters and each book contained 1000 pages, then 3300 such books would be required to store the information of DNA sequence from a single human cell. The enormous amount of data expected to be generated also necessitated the use of high speed computational devices for data storage and retrieval, and analysis. HGP is a mega project involving the co-ordinations of many laboratories of world.
