How Space Might Have Shaped Our DNA

The video explores why DNA is predominantly right-handed, delving into the concept of chirality in nucleotides and the potential influence of cosmic rays on electron spin. It discusses how left-handed nucleotides might have been more prevalent due to cosmic radiation, leading to the evolutionary preference for right-handed DNA helices. The video also highlights experiments that suggest electron asymmetry could have played a role in this molecular bias.

What is the significance of DNA being predominantly right-handed in all living organisms?

Explain the concept of chirality in relation to DNA nucleotides.

What role do cosmic rays play in the formation of left-handed and right-handed DNA?

Why have right-handed electrons never been observed in nature according to the text?

Discuss the potential evolutionary advantages of left-handed DNA nucleotides.
