Ribosomes are made up of _ and _.
Correct answer: A. RNA and protein
- A. RNA and protein
- B. RNA and lipids
- C. RNA and carbohydrates
- D. Proteins and carbohydrates
Explanation
Ribosomes are complex molecular machines found within all living cells that perform biological protein synthesis (translation). They are primarily made up of ribosomal RNA (rRNA) and proteins, forming ribonucleoprotein particles. This composition allows them to facilitate the linking of amino acids to form proteins. The incorrect options either include lipids or carbohydrates, which are not components of ribosomes.
