biology 1: cell biology
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.
