Where can I find the human DNA sequence?

Question

I have looked on the Human Genome Project website, and yet, I am unable to find a link anywhere where I can download the entire nitrogen base sequence of a chromosome (just plainly and simply laid out in terms of ATGC). Do you know where I can go? Preferrably, this would be an online reference that I could download, as apposed to a book, because my end goal is to get all of the information in a manipulatable text or word processor document.

Answer 1

Look at it this way, the genome itself is compared to the length of 800 Bibles.

One chromosome is roughly 17.5 Bibles long.

My bible is well over a thousand pages long.

Answer 2

No. They likely won't use the "God is testing us" or "It's work of the devil!" excuses. They're starting to catch on that its foolish, what with all the hysterical laughing we do when they say such ludicrous things. They will likely dismiss it as evidence of God! They'll say retroviral DNA is purposefully put in our genomes. They'll use that analogy to cars; that the parts to two different models may be the same, but it doesn't mean they "evolved" from a common source, only that the two models are "created" by the same car maker. They don't understand that through very specific methods of DNA sequency (like gel electrophoresus) we can see that humans and chimps have these retroviral inserts (technically called transposons) at the SAME place in the sequence. It is highly unlikely that two separate transposons inserted themselves individually into two separate species in the exact same place. ***** Well now they aren't necessarily *completely* useless. Only 15% of anyone's DNA actually codes for a functional polypeptide. A good 40% of our DNA is... well... useless. Or it would seem! We now speculate that these huge gaps of "non-coding DNA" allows more wiggle room for otherwise fatal mutations. If 100% of your DNA is absolutely necessary for you as an organism to exist, then any mutation to your DNA would be an EXTREME RISK to your existence. There is a chance that such retroviral transposons are being selected for (via Natural Selection of course) for this same reason. ****** Dude! Look at these answers! Did I call it or what! YOu see! I know these Fundies all too well.

Answer 3

I would not download an entire chromosome, let alone an entire genome, for several reasons -

a) too big.... it would take a bit of time and a lot of hard drive space!

b) it's really only a framework, and there's a lot of variation in there, plus lots of really irrelevant junk too.

c) better viewed in context.. look at a sequence in terms of just a gene or a gene group and compare it to other species or other individuals of the same species to see the differences.

Why do you want to download an entire chromosome sequene anyway? You want a blueprint for a "bake your own"? :)

Just enter the sequence of interest into GenBank (via NCBI homepage) and compare it to others.

I do research in a genetics lab and nobody ever bothers to download an entire genome and rarely an entire chromosome - we just don't need to! The NCBI servers store all that infomation and you just download the bits you need.

http://www.ncbi.nlm.nih.gov/

NCBI is a tool often used by researchers. You can scan the primary literature, if you BLAST a sequence, you can see what organisms' genomes it matches, etc.

Answer 5

Did some searching and the best I found was a code in this document: http://ivan.research.ucf.edu/SOE/SOE009.pdf

Good luck though. ^_^;;
