Question

multiple choice 1 point
which statement best describes the relationship that exists among proteins, dna, and cells?
○ cells contain dna, which controls the production of proteins.
○ proteins are made up of dna, which determines the cells that are produced.
○ dna is made up of proteins, which tell a cell how to function.
○ proteins combine to produce cells, which produce dna.

Explanation:

Cells contain DNA, which is the genetic material. DNA has the instructions (genes) that control the production of proteins. Proteins are important molecules in cells that perform various functions. The first option is incorrect as proteins don't combine to produce DNA. The second option is wrong because DNA is not made up of proteins; rather, DNA codes for proteins. The third option is incorrect as proteins are not made up of DNA; DNA provides the blueprint for protein synthesis.

Answer:

Cells contain DNA, which controls the production of proteins.
