Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Ribosomes are sites of
A
Protein synthesis
B
Chlorophyll synthesis
C
Carbohydrate synthesis
D
None of the above
Explanation: 

Detailed explanation-1: -The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence. Ribosomes use cellular accessory proteins, soluble transfer RNAs, and metabolic energy to accomplish the initiation, elongation, and termination of peptide synthesis.

Detailed explanation-2: -A ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell. The ribosome reads the messenger RNA (mRNA) sequence and translates that genetic code into a specified string of amino acids, which grow into long chains that fold to form proteins.

Detailed explanation-3: -Nucleolus is the site of ribosome synthesis. Note:Nucleolus is a special dense region in the eukaryotic cell. It is composed of RNA and protein.

Detailed explanation-4: -Ribosomes can be found as free structures in the cytoplasm or strung along mRNA molecules as they participate in protein synthesis.

Detailed explanation-5: -Ribosomes are the sites of protein synthesis in both prokaryotic and eukaryotic cells.
