Many ribosomes may associate with a single mRNA to form multiple copies of a polypeptide simultaneously . Such strings of ribosomes are termed as
Plastidome
Polyhedral bodies
Polysome
Nucleosome
As we learnt in
Ribosomes -
It is a complex made up of RNA and protein and is the site for protein synthesis.
- wherein
Several ribosomes may attach to a single mRNA and form chains called polyribosomes or polysome.
The phenomenon of association of many ribosomes with single m-RNA leads to formation of polyribosomes or polysomes or ergasomes.
Option 1)
Plastidome
This is incorrect.
Option 2)
Polyhedral bodies
This is incorrect.
Option 3)
Polysome
This is correct.
Option 4)
Nucleosome
This is incorrect.
