  Hey! 👋
  
  Genes in humans are made of DNA (deoxyribonucleic acid), a molecule composed of nucleotides (A, T, C, G). These nucleotides are arranged in specific sequences that encode instructions for making proteins.
  
  Scientifically:
  
  DNA is structured as a double helix (Watson & Crick, 1953).
  
  Each gene is a segment of DNA located on a chromosome.
  
  Genes are inherited from parents through meiosis and fertilization.
  
  So, genes = specific DNA sequences that code for traits. 🧬
