Verified step by step guidance
1
Understand the basic structure of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.
Recognize that nucleic acids are polymers made up of nucleotide monomers linked together.
Learn that dehydration synthesis, also known as a condensation reaction, is the process that links nucleotides together. This involves the removal of a water molecule.
In dehydration synthesis, the hydroxyl group (OH) from the phosphate of one nucleotide and a hydrogen (H) from the sugar of another nucleotide are removed, forming a water molecule (H₂O).
The remaining oxygen from the phosphate group forms a covalent bond with the sugar, creating a phosphodiester linkage, which is the backbone of nucleic acid strands.
