Guida verificata passo dopo passo1
Understand the composition of each cellular structure mentioned in the problem.
Ribosomes are composed of ribosomal RNA (rRNA) and proteins, not solely DNA and proteins.
The cytoskeleton is made up of protein filaments such as actin and tubulin, not DNA.
The cell membrane is primarily composed of a lipid bilayer with embedded proteins, and does not contain DNA.
Chromatin is the correct answer as it is composed of DNA wrapped around histone proteins, making it solely composed of DNA and proteins.
