Test your knowledge with these top questions!
Question 1
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.
Question 2
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.
Question 3
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.
Question 4
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.
