Front

What is the function of mRNA?

Back

To carry genetic information from DNA to the ribosome for protein synthesis.

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 four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the process of DNA replication?

Back

The process by which a DNA molecule makes a copy of itself.

Front

What is the role of ribosomes in protein synthesis?

Back

To translate mRNA into a polypeptide chain (protein).
