The GC content of the human genome is approximately 41%. This means that 41% of the bases in the human genome are either guanine (G) or cytosine (C), while the remaining 59% are adenine (A) or thymine (T).

It's important to note that:

* GC content varies across the genome: Different regions of the genome can have significantly different GC content. For example, gene-rich regions tend to have higher GC content than gene-poor regions.

* This is an average: The 41% figure is an average across the entire genome. Individual chromosomes and even specific genes can have different GC contents.
