Ribosomes are composed of almost an equal amount of:

Explanation

Option A: Protein & Lipid: Ribosomes are not composed of almost equal amounts of protein and lipid. In fact, lipids are only found in small amounts in the membranes of ribosomes. The major components of ribosomes are protein and RNA. Option B: Protein & RNA: Ribosomes are composed of almost equal amounts of protein and RNA. The protein component of ribosomes is made up of about 50 different proteins, while the RNA component is made up of three different RNA molecules. The RNA molecules in ribosomes are called ribosomal RNA (rRNA). Option C: RNA & Lipid: Ribosomes are not composed of almost equal amounts of RNA and lipid. In fact, lipids are only found in small amounts in the membranes of ribosomes. The major components of ribosomes are RNA and protein. Option D: RNA & Carbohydrates: Ribosomes are not composed of almost equal amounts of RNA and carbohydrates. In fact, carbohydrates are not found in ribosomes at all. The major components of ribosomes are RNA and protein.
