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: -Ribosomes have two main functions-decoding the message and the formation of peptide bonds. These two activities reside in two large ribonucleoprotein particles (RNPs) of unequal size, the ribosomal subunits. Each subunit is made of one or more ribosomal RNAs (rRNAs) and many ribosomal proteins (r-proteins).

Detailed explanation-3: -The purpose of protein synthesis is simply to create a polypeptide–a protein made out of a chain of amino acids. In a hair follicle cell, a protein called keratin is made. Lots of it. Many ribosomes can be working on a single strand of mRNA at once.

Detailed explanation-4: -So, the correct answer is Both prokaryotes and eukaryotes’.
