A polyribosome (or polysome or ergosome) is a group of ribosomes bound to an mRNA molecule like “beads” on a “thread”. ... Multiple ribosomes move along the coding region of mRNA, creating a polysome. The ability of multiple ribosomes to function on an mRNA molecule explains the limited abundance of mRNA in the cell.

What is a polysome in biology?

Polysomes are aggregates of numerous ribosomes that are in the process of actively translating mRNA into protein. By light microscopy polysomes appear as basophilic cytoplasmic granules, but are extremely labile during postmortem change in the liver.

Which of the statement define polysomes?

7. Which of the following statement is defines polysomes? Explanation: Polysome is also known as polyribosome, it is a structure where a single mRNA holds a number of ribosomes translocating in 5' to 3' direction.
