Back

Amino acids.

Front

What is the role of RNA in protein synthesis?

Back

RNA acts as a messenger carrying instructions from DNA for controlling the synthesis of proteins.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are the sites of protein synthesis.

Front

What is the difference between DNA and RNA?

Back
