Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the location in the cell for translation?
A
nucleus
B
mitochondria
C
ribosome
D
chloroplast
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: -During transcription, a piece of DNA that codes for a specific gene is copied into messenger RNA (mRNA) in the nucleus of the cell. The mRNA then carries the genetic information from the DNA to the cytoplasm, where translation occurs.

Detailed explanation-3: -Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins. The ribosome has a small and a large subunit and is a complex molecule composed of several ribosomal RNA molecules and a number of proteins.

Detailed explanation-4: -The nuclear envelope of eukaryotic cells separates the nucleus and cytoplasm. It is thought to partition transcription and processing of messenger RNAs (mRNAs), which occur in the nucleus, from protein synthesis (translation), which is observed in the cytoplasm.

Detailed explanation-5: -Ribosomes are found ‘free’ in the cell cytoplasm and also attached to rough endoplasmic reticulum. Ribosomes receive information from the cell nucleus and construction materials from the cytoplasm. Ribosomes translate information encoded in messenger ribonucleic acid (mRNA).
