Explain why the $Human$ $Genome$ $Project$ is considered a 'mega project'.

(N/A) The $Human$ $Genome$ $Project$ $(HGP)$ is called a 'mega project' due to the following reasons:
$1$. The human genome contains approximately $3 \times 10^9$ base pairs. If the cost of sequencing is $3$ $US$ dollars per base pair,the total estimated cost of the project would be approximately $9$ billion $US$ dollars.
$2$. If the sequences obtained were to be stored in books,and each book contained $1000$ pages with $1000$ letters on each page,it would require $3300$ such books to store the information of the $DNA$ from a single human cell.
$3$. The massive amount of data generated requires high-speed computational devices for storage,retrieval,and analysis,which necessitates significant infrastructure and interdisciplinary collaboration.
