Hint: Microbes have genomes, which are mostly smaller than those of macroscopic creatures like humans. Base pairs are used to calculate DNA. The human genome, for example, is 3.4 billion base pairs long, while Escherichia coli, a common intestinal bacteria, is 4.6 million base pairs long.

The chemical formula can be used to measure the weight of nucleotide bases, and relative weights can be used to compare the weight with the estimated number of bases in a given sample of DNA. Using this method, it was calculated that one nucleotide pair has a mean weight of $1.023 \times {10^9}pg$, and $1pg$ of DNA represents$978000000$ base pairs.
$(978000000) \times$ (number of nucleotide pairs) is the right formula for translating picograms of DNA to nucleotide pairs (DNA content in picograms).
A lower valuation has been stated by some employees $(965000000)$which is $0.965 \times {10^9}$.
