  1. Question 1

    Q1. During an electron microscopy session, a student observes ribosomes inside a mitochondrion. What is the sedimentation coefficient of these specific ribosomes?

    • A) 40S
    • B) 60S
    • C) 70S
    • D) 80S

    Answer: 70S

    Explanation: Mitochondria contain 70S ribosomes, an anomaly within eukaryotic cells that typically possess 80S ribosomes in their cytosol.
