Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which best describes where the process of translation happens within a living cell?
A
in the nucleus
B
at a ribosome in the cytoplasm
C
in a mitochondrion near a ribosome
D
on the vacuole attached to the nucleus
Explanation: 

Detailed explanation-1: -Translation takes place on ribosomes in the cell cytoplasm, where mRNA is read and translated into the string of amino acid chains that make up the synthesized protein.

Detailed explanation-2: -Translation refers to the processing of an mRNA script into a protein. This process utilizes ribosomes and tRNA. In translation, messenger RNA (which is produced by transcription from DNA) is decoded by a ribosome to produce a specific amino acid chain, or polypeptide.

Detailed explanation-3: -Where Translation Occurs. Within all cells, the translation machinery resides within a specialized organelle called the ribosome. In eukaryotes, mature mRNA molecules must leave the nucleus and travel to the cytoplasm, where the ribosomes are located.

Detailed explanation-4: -Translation is the process of protein synthesis and occurs on ribosomes where mRNA come from the nucleus and attached to the ribosome and in the presence of ribozyme and tRNA in ribosome mRNA translates the codon for protein synthesis.

Detailed explanation-5: -The eukaryotic nucleus therefore provides a distinct compartment within the cell, allowing transcription and splicing to proceed prior to the beginning of translation. Thus, in eukaryotes, while transcription occurs in the nucleus, translation occurs in the cytoplasm.
