DNA Fact of the Day 🧬
DNA is made of three main components:
• Sugar
• Phosphate
• Nitrogen bases (A, T, C, G)
These combine to form the double helix structure that carries genetic information for every living person.
Fun fact:
Humans share 99.9% of the same DNA.
That tiny 0.1% difference is what allows DNA testing to identify family relationships with incredible accuracy.
Science is pretty amazing.
