The claim that human DNA is 3GB is false. I assume the assumption was that 3 billion base pairs equates to 3GB.
There are a few issues with this: 1. DNA is a quaternary sequence, not a binary sequence (Adenine, Guanine, Cytosine, Thymine). 3 Billion base pairs are informationally equivalent to 6 billion bits. 2. Human haploid cells have a single set of chromosomes composed of ~3 billion base pairs. However, somatic cell's are diploid with 2 sets of chromosomes composed of 6 billion base pairs. The bases present at each allele are not identical and allele comb... (read more)
