Q.

Many ribosomes may associate with a single mRNA to form multiple copies of a polypeptide simultaneously. Such strings of ribosomes are termed as        [2018]

1 polysome  
2 polyhedral bodies  
3 plastidome  
4 nucleosome

The association of many ribosomes with single mRNA leads to formation of polyribosomes or polysomes. It occurs during translation process of protein synthesis.
