Polyribosomes are aggregates of (a) ribosomes and rRNA (b) only rRNA (c) peroxisomes (d) several ribosomes held together by string of mRNA.
Option D Polyribosomes are aggregates of several ribosomes held together by string of mRNA. Polyribosomes consists of 4 8 ribosomes which are attached to a single strand of messenger RNA or mRNA. This mechanism help in synthesis of several copies of the same protein.
