Question

which cellular part contains the instructions that cells need to make proteins?
a dna
b cytoplasm
c cell membrane
d ribosomes

Explanation:

DNA contains the genetic code which provides instructions for making proteins through the processes of transcription and translation. The cytoplasm is the site of many cellular processes but does not hold the protein - making instructions. The cell membrane is mainly involved in cell - to - cell communication and regulating what enters and leaves the cell. Ribosomes are the sites where proteins are synthesized, but they do not contain the instructions themselves.

Answer:

A. DNA
