If 3 ribosomes attach to single mRNA at different points then how many similar proteins will from?
Correct answer: C. 3
- A. 1
- B. 2
- C. 3
- D. No similar protein
Explanation
Polysomes, or polyribosomes, are several ribosomes attached to a single mRNA molecule, each translating the mRNA into identical copies of a protein. In this scenario, three ribosomes attached to the mRNA will produce three identical proteins. Option A is incorrect because it suggests only one protein is made, which is not the case when multiple ribosomes are involved. Option B is incorrect as it implies one ribosome is inactive. Option D is incorrect because it suggests no protein is produced, contrary to the function of ribosomes in protein synthesis.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
