Explanation:
Detailed explanation-1: -Once assembled, ribosomes are transported to the cell cytoplasm, where they serve as the sites for protein synthesis.
Detailed explanation-2: -Ribosomes are found ‘free’ in the cytoplasm or bound to the endoplasmic reticulum (ER) to form rough ER. In a mammalian cell there can be as many as 10 million ribosomes. Several ribosomes can be attached to the same mRNA strand, this structure is called a polysome.
Detailed explanation-3: -Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum. Their main function is to convert genetic code into an amino acid sequence and to build protein polymers from amino acid monomers.
