Which statements describe proteins? Select three options.

Question

Proteins are created from the code in DNA.
Proteins are synthesized in the nucleus of a cell.
DNA and RNA are proteins.
Amino acids are the building blocks of proteins.
Proteins affect the structures and functions of living things.
The shape and the function of a protein are not related.

Answer 1

The three statements that correctly describe proteins are:

1. Proteins are created from the code in DNA.
2. Amino acids are the building blocks of proteins.
3. Proteins affect the structures and functions of living things.

The other statements are incorrect: proteins are synthesized in the ribosomes (not the nucleus), DNA and RNA are types of nucleic acids (not proteins), and the shape and function of a protein are indeed related.
