Question

Polyribosomes are ______ 

Options

• A total number of ribosomes in the cell.

• A number of ribosomes are linked to mRNA.

• Not capable of helping in the synthesis of the polypeptide chain.

• Devoid of rRNA.

Answer 1

Polyribosomes are A number of ribosomes linked to mRNA.

Explanation:

Polyribosomes are a number of ribosomes linked to mRNA strands. lt increases the efficiency of protein synthesis as many polypeptides can be synthesized simultaneously. In bacteria, they are found free in the cytoplasm, and in eukaryotes, they are attached to RER and the outer membrane of the nucleus.
