Detailed explanation-1: -A ribosome is the cellular machinery responsible for making proteins. There are many ribosomes in each cell, each made up of two subunits. These two subunits lock around the messenger RNA and then travel along the length of the messenger RNA molecule reading each three-letter codon.

Detailed explanation-2: -The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence. Ribosomes use cellular accessory proteins, soluble transfer RNAs, and metabolic energy to accomplish the initiation, elongation, and termination of peptide synthesis.

Detailed explanation-3: -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.

Detailed explanation-4: -There are two types of ribosomes, free and fixed (also known as membrane bound). They are identical in structure but differ in locations within the cell. Free ribosomes are located in the cytosol and are able to move throughout the cell, whereas fixed ribosomes are attached to the rER.
