● Some of the `color{VioletBrown}"salient observations"` drawn from human genome project are as follows:
(i) The human genome contains `color{Violet}"3164.7 million"` nucleotide `color{Violet}"bases"`.
(ii) The average gene consists of `color{Violet}"3000 bases"`, but sizes vary greatly, with the `color{Violet}"largest"` known human gene being `color{Violet}"Dystrophin"` at `color{Violet}"2.4 million bases"`.
(iii) The total number of genes is estimated at `color{Violet}"30,000"`–much lower than `color{Violet}"previous estimates"` of 80,000 to 1,40,000 genes.
(iv) Almost all (`color{Violet}"99.9 per cent"`) nucleotide bases are `color{Violet}"exactly the same"` in all people.
(v) The `color{Violet}"functions are unknown"` for over `color{Violet}"50 per cent"` of discovered genes.
(vi) `color{Violet}"Less than 2 per cent"` of the genome codes for `color{Violet}"proteins"`.
(vii) `color{Violet}"Repeated sequences"` make up very `color{Violet}"large portion"` of the human genome.
(viii) `color{Violet}"Repetitive sequences"` are stretches of DNA sequences that are `color{Violet}"repeated many times"`, sometimes hundred to thousand times.
(ix) They are thought to have `color{Violet}"no direct coding functions"`, but they shed light on `color{Violet}"chromosome structure"`, `color{Violet}"dynamics"` and `color{Violet}"evolution"`.
(x) `color{Violet}"Chromosome 1"` has most genes (`color{Violet}"2968"`), and the `color{Violet}"Y"` has the fewest (`color{Violet}"231"`).
(xi) Scientists have identified about `color{Violet}"1.4 million locations"` where single base DNA differences (`color{Violet}"SNPs"` – `color{Violet}"single nucleotide polymorphism"`, pronounced as `color{Violet}"snips"`) occur in humans.
● This information promises to `color{Violet}"revolutionise"` the processes of finding `color{Violet}"chromosomal locations"` for `color{Violet}"disease-associated sequences"` and `color{Violet}"tracing human history"`.
