Detailed explanation-1: -The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
Detailed explanation-2: -The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence.
Detailed explanation-3: -Explanation : Nucleolus is a darkly pigmented portion of nucleus . It produces rRNA which moves from there to cytoplasm and join with proteins to form ribosomes. So it concludes that nucleolus is the portion of cell which forms ribosomes.
Detailed explanation-4: -Ribosomes are specialized cell organelles and are found in both prokaryotic and eukaryotic cells. Every living cell requires ribosomes for the production of proteins.
Detailed explanation-5: -Synthesis of new proteins starts in the nucleus, where ribosomes get their instruction to begin the process. Sections of DNA (genes), encoding a specific protein, are copied over to messenger RNA (mRNA) strands in a process called transcription.
