Give any six features of the human genome.

(N/A) Some of the salient observations drawn from the 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 $30,000$,which is much lower than previous estimates of $80,000$ to $1,40,000$ genes. Almost all ($99.9$ percent) nucleotide bases are exactly the same in all people.
$(iv)$ The functions are unknown for over $50$ percent of the discovered genes.
$(v)$ Less than $2$ percent of the genome codes for proteins.
$(vi)$ Repeated sequences make up a very large portion of the human genome.
