NEET BIOLOGY

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: -Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis-the stitching together of amino acids to make a protein molecule.

Detailed explanation-3: -Ribosome: a micro-machine for manufacturing proteins About two-thirds of this mass is composed of ribosomal RNA and one third of about 50+ different ribosomal proteins. Ribosomes are found in prokaryotic and eukaryotic cells; in mitochondria, chloroplasts and bacteria.

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: -The nucleus (plural, nuclei) houses the cell’s genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins.
