Protein synthesis in an animal cell, takes place:
Protein synthesis in an animal cell, takes place:
Updated On: Sep 4, 2024
- only in the cytoplasm
- in the nucleolus as well as in the cytoplasm
- in the cytoplasm as well as in mitochondria
- only on ribosomes attached to nucleus
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Mitochondria also contain own protein synthesizing machinery (m-DNA, mito ribosomes, enzymes) and carry out the synthesis of a limited number of proteins.

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.
