Interesting Facts About Genetics and DNA

Humans share about 60% of their DNA with bananas.

Genes make up only 1-2% of the human genome, with the rest being non-coding sequences often referred to as 'junk DNA'.

The DNA in a single human cell stretches out to be about 2 meters long if uncoiled, yet it fits into a microscopic nucleus.

Every person has about 3 million genetic variations that make their DNA unique from any other human.

Identical twins share nearly all of their DNA, yet they can have different fingerprints due to environmental factors during development.

The genome of a pufferfish is one of the smallest known vertebrate genomes, yet it contains almost the same number of genes as humans.

Genetic mutations have been one of the driving forces of evolution, helping species adapt over time.

The study of epigenetics reveals that environmental factors, such as diet and stress, can influence gene expression without changing the DNA sequence.
