Q. Polysome is formed by
A) Ribosomes attached to each other in a linear arrangement
B) Several ribosomes attached to a single mRNA
C) Many ribosomes attached to a strand of endoplasmic reticulum
D) A ribosome with several subunits
Explanation
[Solution from source] A polysome (polyribosome) is a chain of several ribosomes translating the same mRNA at the same time. The ribosomes are linked through the mRNA, not directly to one another, and ribosomes bound to ER form rough ER rather than a polysome. Answer (2).
