GENERAL HISTOLOGY

Detailed explanation-1: -The Nucleolus-The nucleolus is a membrane-less organelle within the nucleus that manufactures ribosomes, the cell’s protein-producing structures.

Detailed explanation-2: -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.

Detailed explanation-3: -Ribosomes are the protein factories of the cell. Composed of two subunits, they can be found floating freely in the cell’s cytoplasm or embedded within the endoplasmic reticulum.

Detailed explanation-4: -The nucleolus is a spherical structure found in the cell’s nucleus whose primary function is to produce and assemble the cell’s ribosomes.

Detailed explanation-5: -During translation, ribosomal subunits assemble together like a sandwich on the strand of mRNA, where they proceed to attract tRNA molecules tethered to amino acids (circles). A long chain of amino acids emerges as the ribosome decodes the mRNA sequence into a polypeptide, or a new protein.
