Back

To act as a messenger carrying instructions from DNA for controlling the synthesis of proteins.

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the building blocks of RNA?

Back

Nucleotides, similar to DNA but with ribose sugar and uracil instead of thymine.
