Answer» The correct option is (a) 1. - Polyribosomes/Polysomes are a group of ribosomes attached to a single mRNA at several points and translate the mRNA into the same copies of a single polypeptide or protein.
- These are developed during the elongation phase in concern with the ribosomes and elongation factors.
- Polysomal profiling is a technique used to determine the level of gene expression.
- These are found either free in the cytosol or attatched to the endoplasmic reticulum.
- Free Polyribosomes synthesise a protein that remains in the cell. eg. Haemoglobin in RedbloodCells while those attached to the Endoplasmic reticulum synthesize proteins for the export from the cell or to be placed in the plasma membrane.
