Question

How many different proteins does the ribosome consist of?

Options

• 60

• 40

• 20

• 80

Answer 1

80

Explanation:

Ribosomes are cellular macromolecular machines dedicated to protein synthesis. They assemble polypeptide chains by linking amino acids in the precise sequence dictated by the codons on messenger RNA (mRNA). Structurally, these organelles are composed of a complex mix of ribosomal RNA (rRNA) and roughly 80 different proteins.
