Test your knowledge with these top questions!
Human DNA, the biological instruction manual, is roughly what percentage identical across all people?
That tiny 0.1% variation accounts for around 3 million genetic differences, which determine our unique physical traits, ancestry, and disease susceptibilities.
Scientists once dismissed most of the human genome as "junk," but this genetic material actually does what?
Rather than being useless, this non-coding DNA contains essential regulatory sequences acting like switches to turn specific genes on or off in different tissues.
The cell nucleus holds most of the human genome, but what energy-producing organelle carries its own DNA?
Mitochondrial DNA is inherited almost exclusively from the mother and is thought to be the remnants of ancient, free-living bacteria engulfed by early cells.
Many modern humans inherited a small portion of their genome from what extinct hominin species?
People of non-African descent typically carry 1 to 2 percent Neanderthal DNA, the result of interbreeding that affects traits like modern immune responses.
