Ribosomes are made up of

• A. DNA and protein
• B. DNA alone
• C. RNA and proteins
• D. RNA and DNA

Ribosomes are essential cellular structures responsible for protein synthesis. They are composed of two main components.

Composition of Ribosomes

The correct answer to your question is:

• C. RNA and proteins

Details on Ribosome Structure

Ribosomes consist of ribosomal RNA (rRNA) and proteins. The rRNA forms the core of the ribosome, while the proteins help stabilize its structure and assist in the translation process. This combination is crucial for the ribosome's function in assembling amino acids into proteins based on the instructions from messenger RNA (mRNA).

Importance of Ribosomes

Without ribosomes, cells would be unable to produce proteins, which are vital for numerous cellular functions, including enzyme activity, structural support, and signaling.
