DNA and ATP
Summary
The content provides an in-depth exploration of DNA structure, emphasizing the molecular components, bonding, and the significance of the 5' to 3' orientation. It also draws a parallel between DNA structure and ATP, highlighting the energy release mechanism in ATP hydrolysis.
- DNA strands are oriented from the 5' carbon to the 3' carbon, with nucleotides adding to the 3' carbon.
- Nucleotides within a DNA strand are joined by covalent bonds, specifically phosphodiester bonds between the phosphate group and the sugar.
- The base attaches to the 1' carbon of the sugar, and the phosphate group attaches to the 5' carbon.
- DNA's double helix structure consists of two antiparallel strands, with complementary bases pairing across the strands.
- ATP shares a similar structure with DNA's nucleotides, containing a five-carbon sugar and a base, but with three phosphate groups, releasing energy upon hydrolysis.
