What is the approximate molecular weight of a ribosome? A) 1 × 10⁵ amu B) 5 × 10⁵ amu C) 1 × 10⁶ amu D) 5 × 10⁶ amu

Question

Quizplus · Accepted Answer

The molecular weight of a ribosome is approximately 2.5-4.5 million Daltons, which is equivalent to 1 × 10^6-1 × 10^7 amu. Ribosomes are composed of two subunits, the small subunit (SSU) and the large subunit (LSU), which consist of different ribosomal RNA (rRNA) molecules and numerous ribosomal proteins. Based on these complex components, the molecular weight of a ribosome is likely to be about 1 × 10^16 amu, which corresponds to the closest option, C (1 × 10^16 amu), among the choices given.
