How large is the human genome?

Best Answers

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). read more

The size of protein-coding genes within the human genome shows enormous variability (Table 2). The median size of a protein-coding gene is 26,288 bp (mean = 66,577 bp; Table 2 in ). For example, the gene for histone H1a (HIST1HIA) is relatively small and simple, lacking introns and encoding mRNA sequences of 781 nt and a 215 amino acid protein (648 nt open reading frame). read more

The size of the human genome is difficult to estimate. Different individuals can have large scale sequence differences so the size of the genome in one individual will differ in size from the genome in another individual. read more
