To do the math, each base pair takes 2 bits (you can use 00, 01, 10, and 11 for T, G, C and A). Multiply that by the number of base pairs in the human genome, and you get 2 * 3 billion = 6,000,000,000 bits. And remember, you have to go from bits to bytes to get to an answer in megabytes. A bit is just a single unit of digital information, but a byte is a sequence of bits (usually 8).
I'm looking for amount of memory in bytes (MB, GB, TB, whatever) required to store a single human DNA. I read a few articles on Wikipedia about DNA, Chromosomes, Base pairs, Genes, and have some rough guess, but before disclosing anything I'd like to see how others would approach this issue.Alternative question would be how many atoms are there in human DNA, but that would be off topic for this site. read a few articles on Wikipedia about DNA, Chromosomes, Base pairs, Genes, and have some rough guess, but before disclosing anything I'd like to see how others would approach this issue.
