The content provides an in-depth exploration of the structure and function of DNA, detailing its components, the bonding between nucleotides, and the significance of the double helix formation. It also draws a parallel between DNA and ATP to elucidate the molecular basis of energy transfer within cells.
  • DNA strands run from the 5 prime to the 3 prime end, with nucleotides adding to the 3 prime carbon.
  • Nucleotides within a DNA strand are joined by covalent bonds, specifically phosphodiester bonds between the phosphate group of one nucleotide and the sugar of the next.
  • The base attaches to the 1 prime carbon of the sugar, and the phosphate group attaches to the 5 prime carbon.
  • DNA's double helix structure consists of two antiparallel strands, with complementary bases bonding across the strands.
  • ATP shares a similar structure with DNA, having the same five carbon sugar and a base, but with three phosphate groups, highlighting its role in energy transfer.
