Question

What is polysome and give its function?

Answer 1

HEYA !! HERE IS UR ANSWER
A polysome is a chain of ribosomes, which are attached to a single strand of mRNA.

Function ---- The ribosome of a polysome translate the mRNA into polypeptides...

hope this will help u


THANK u☺

Answer 2

Answer:

Polysome is a structure formed from when a single mRNA (messenger RNA) is translated into multiple polypeptide chains by multiple ribosomes at the same time.

Explanation:

• A single copy of mRNA can give rise to multiple copies of polypeptide chains.
• This happens when multiple ribosomes translate the single mRNA simultaneously at the same time.
• Different ribosomes bind to the translation initiation site on the mRNA at different time, initiate and then elongate the polypeptide chain.
• Polysomes are usually observed on the mRNAs which are essential for survival and metabolism of the cells.
• They are also found on those mRNAs whose concentration in the cell is low.
