Question:
Polyribosomes are aggregation of
Polyribosomes are aggregation of
Updated On: Jul 25, 2024
- ribosomes and $ r RNA$
- peroxisomes
- several ribosomes held together by a string of $mRNA$
- $rRNA$
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Ribosomes may occur singly as monosomes or in rosettes and helical groups called polyribosomes. The different ribosomes are connected with a $10 - 20?$ thick strand of $ mRNA$. They are formed during periods of active protein synthesis when a number of copies of the same polypeptide are required

- Consider the diameter of a spherical object being measured with the help of a Vernier Callipers. Suppose its 10 Vernier Scale Divisions (V.S.D.) are equal to its 9 Main Scale Divisions (M.S.D.). The least count in the M.S. is 0.1 cm and the zero of V.S. is at -0.1 cm when the jaws of Vernier callipers are closed. If the main scale reading for the diameter is \(M = 5\) cm and the number of coinciding vernier division is 8, the measured diameter after zero error correction, is:

Concepts Used:
Translation
The translation is the process of converting nucleic acid information into amino acids. It also relates to the process of producing proteins from mRNA templates.
Components of Translation:
The main components of translation include :
- mRNA of both Eukaryotes and Prokaryotes
- tRNA - It helps in sending commands or transferring the information between protein and nucleic acids.
- Ribosomes - It contains ribosomal RNA and proteins, therefore, it is called the manufacturing unit of a cell.
- Enzymes - It is required for the formation of a peptide bond between the amino acids and also to attach amino acids to the accurate tRNA molecules.
- Proteins - They are the soluble factors, which are required for proper initiation, elongation and termination of translation.
Translation Process:
The three stages of translation are-
- Initiation involves assembling ribosomes around mRNA and activating amino acid and delivering it to the transfer RNA.
- Elongation is the process in which the RNA strand gets longer by adding amino acids.
- The termination process only involves releasing a polypeptide chain.
