What was the estimated number of genes in the human genome (in $,000$)?

The dystrophin gene has ...... bases.

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

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

The approach of identifying all the genes that are expressed as $RNA$ and then determining the functions of all the coding and non-coding sequences in the genome is known as .........

The method of identifying all the genes that are expressed as $\text{RNA}$ is referred to as:
