Question

dna structure and function assignment (cw)
which statements best describe the relationship between cells, dna, and proteins?
dna is composed of proteins that carry coded information for how cells function.
cells contain dna that controls the production of proteins.
proteins are used to produce cells that link amino acids together into dna.
cells are linked together by proteins to make different kinds of dna molecules.

Explanation:

DNA is the genetic material in cells. It contains the instructions for making proteins through the processes of transcription and translation. Proteins are made up of amino - acids and perform various functions in the cell. Cells contain DNA which controls protein production. The first option is incorrect as DNA is composed of nucleotides, not proteins. The third option is wrong because DNA is used to produce proteins, not the other way around. The fourth option is incorrect as cells are not linked by proteins to make DNA molecules.

Answer:

Cells contain DNA that controls the production of proteins.
