Backbone: In DNA, the backbone refers to alternating sugar-phosphate units that make up each strand. It provides structural support and stability for maintaining the integrity of the double helix.
Phosphodiester Bond: These bonds link adjacent nucleotides in the DNA backbone. They form between the phosphate group of one nucleotide and the sugar molecule of the next nucleotide.
Nucleic Acids:Phosphates are an essential component of nucleic acids, which are biological macromolecules that include DNA and RNA. Nucleic acids store and transmit genetic information.
