Back

Dehydration synthesis.

Front

What is hydrolysis?

Back

Hydrolysis is the process of breaking down polymers into monomers by adding water.

What is the role of the phosphate group in nucleic acids?

Back

The phosphate group links the sugar of one nucleotide to the sugar of the next nucleotide.
