Fascinating DNA Facts

🧬

99.9% Identical

Human DNA is 99.9% identical between individuals - we differ by only 0.1%

📏

6 Feet Per Cell

If uncoiled, DNA from one cell would stretch 6 feet - your body has ~37 trillion cells

🦠

20-Minute Replication

E. coli bacteria can replicate their entire genome in just 20 minutes

💾

215 Petabytes

1 gram of DNA can theoretically store 215 petabytes of data

🌍

Universal Code

All life on Earth uses the same 4 nucleotides: A, T, G, C (or U in RNA)

🧫

GC Stability

GC-rich DNA has a higher melting temperature due to 3 hydrogen bonds vs 2 for AT

🔬

PCR Power

PCR can amplify a single DNA molecule to billions of copies in hours

🦘

Banana Cousins

Humans share 60% of their DNA with bananas - genes are universal building blocks
