Proteins run our show. Muscles, organs, hair, bone, and skin either contain or are made of proteins. They are a major component in all of our cells. Enzymes that run the chemical reactions in our bodies are proteins. Proteins help us move, send messages (hormones and nerve receptors), fight off disease (antibodies), and transport other molecules and atoms around our bodies.
A protein is a molecule that consists of a chain of amino acids. There are 21 different amino acids to choose from, and the genetic information in our DNA determines how they're put together. A single protein consists of hundreds of amino acids, all folding into a structure with a specific shape.
Important Parts Used In Protein Synthesis
Important Parts Used In Protein Synthesis
Nucleus = This is where the DNA is kept in each cell.
The nucleus is like a library that holds all of the information about you.
DNA (Deoxyribonucleic Acid) = This is like a master reference/recipe/instruction book that explains how you are built.
They are the blueprints of your body.
Genes are like chapters.
Messenger RNA = This is like a photocopy of the plans/recipes/instructions.
The MRNA travels from the nucleus to the ribosome where it will be used to construct important body proteins.
Messenger RNA are copies of DNA. The DNA stays put in the nucleus, but the mRNA copies can leave.
The mRNA is a copy of DNA that is used to make protein.
Amino Acids = These are the building supplies that are used to make proteins.
There are 21 amino acids that our bodies use to make protein.
Observe the different kinds below:
Amino acids are like bricks that build protein.
These 21 amino acids combine to form all proteins in your body. Amino acids are like bricks.
Transfer RNA = These are like trucks that carry amino acids (building supplies) to the ribosome.
tRNA

Ribosomes = These are the construction sites found in the cytoplasm of every cell where proteins are assembled.
They are like work desks. They are like machines that make important products. They make protein.

Amino acids (bricks) are put together at the ribosomes. Proteins are put out on the other end.
Proteins = These are the finished product that your body uses to live.
