The Human Genome Project (completed in the early 2000s) sequenced and mapped the entire human genome and estimated its size at approximately 3164.7 million (~3.1 billion) base pairs (bp), spread across 23 pairs of chromosomes, encoding roughly 30,000-25,000 genes (a much smaller number than base pairs, since most of the genome is non-coding). 35 million (a) and 3.5 million (b) are far too small to represent the whole genome's base-pair count, and 35,000 (d) is closer to (an older, since-revised) estimate of gen …
