When was the sequencing of chromosome $1$ completed?

Which new field was made possible to expand rapidly due to the $HGP$?

In the Human Genome Project, among the two major approaches for sequencing the whole set of the genome, the one that contained all the coding and non-coding sequences and later assigned different functions to different regions in the sequence is called . . . . . . .

The total number of genes in humans is far less $(< 25,000)$ than the previous estimate (up to $1,40,000$ genes). Comment.

According to the Human Genome Project $(HGP)$, the total number of genes in the human genome is estimated at $30,000$. The number of genes on the $Y$ chromosome is: (in $genes$)

The number of nitrogenous bases in the human genome is approximately ...... .
