Front

What is the primary function of proteins in the cell?

Back

Proteins serve as enzymes, structural components, and play roles in signaling and transport.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of nucleotides, which include a sugar, phosphate group, and nitrogenous base.

Front

What are the base pairing rules in DNA?

Back

Adenine pairs with Thymine, and Cytosine pairs with Guanine.
