I am a student in Information Systems at the university of Geneva.
I'd like to know how many hard disk space would be necessary to store a
entire human genome.
If I have well understood, in all our 46 chromosomes we have 3 * 10^9
bases. Each base is an A, C, G or T.
Are they other elements that should be stored? Would it be enough?
So, a human genome would take less than 1 GB disk space :
- 4 letters can be encoded on 2 bits
- 2 * (3 * 10^9) / 8 / 1024 / 1024 = 715 MB
Is that right ???
