Question

if 3 ribosomes attach with single mRNA at different points , how many similar proteins may form ?
A. 1 protein
B. 2 protein
C. 3 protein
D. not form any protein​

Answer 1

Answer:

A. 1 protein.

Explanation:

Many Ribosomes can attach themselves to a single strand of mRNA and the structure will called POLYSOME and single mRNA strand can only form 1 Protein.

Answer 2

The Correct Solution is Option A, one protein.

• 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.
