Detailed explanation-1: -The ribosomes are the protein makers of the cell. They receive messages from the nucleus. The nucleus tells the ribosome what kinds of proteins to make and when to make them. There are two types of ribosomes: free ribosomes and bound ribosomes.

Detailed explanation-2: -What looks like a jumble of rubber bands and twisty ties is the ribosome, the cellular protein factory. The ribosome is made up of proteins and strands of RNA, a chemical relative of DNA. It has two interlocked parts that behave as a single molecular machine to assemble all of the cell’s protein molecules.
