Give any six features of the human genome.
Some of the salient Observations drawn from human genome project are as follows:
$(i)$ The human genome contains $3164.7$ million nucleotide bases.
$(ii)$ The average gene consists of$3000 $bases, but sizes vary greatly, with the largest known human gene being dystrophin at $2.4$ million bases.
$(iii)$ The total number of genes is estimated at $30,000$ -much lower than previous estimates of 80,000 to $1,40,000$ genes. Almost all ($99.9$ per cent) nucleotide bases are exactly the same in all people.
$(iv)$ The functions are unknown for over $50$ per cent of the discovered genes.
$(v)$ Less than $2$ per cent of the genome codes for proteins.
$(vi)$ Repeated sequences make up a very large portion of the human genome.
How has the sequencing of human genome opened new windows for treatment of various genetic disorders. Discuss amongst your classmates.
Expressed Sequence Tags (ESTs) refers to
Give scientific reasons : $DNA$ polymorphism is the basis of genetic mapping of human genome.
The total number of genes in humans is far less $(< 25,000)$ than the previous estimate (upto $1,40,000$ gene). Comment.
