To answer this question we have to talk a process called: "Translation". After the "Transcription", that is, the mechanism from where a mRNA molecule is synthesized from a DNA double helix. The mRNA molecule migrates outside the nucleus to the cytoplasm and specifically to the ribosomes (a complex protein organelles that serve as building machines for new polypeptide molecules). The mRNA molecule carries the specific sequence for the synthesis of the new polypeptide (protein) chain and serves as a "template" for the proper order of the amino acids that will constitute the new protein molecule. To add the amino acids to the growing polypeptide chain are necessary the tRNA molecules (these RNA structures carry a single amino acid that will be added to the growing polypeptide chain). Each tRNA has a specific three-nucleotide sequence (called "anticodon") that recognizes the corresponding three-nucleotide sequence (codon) on the mRNA molecule. Each amino acid monomer (carried by its particular tRNA) is anchored, one by one, to the previous amino acid that was added before by a peptide bond. This mechanism is taken place in a particular region of the ribosome, a cleft that provides the nascent polypeptide's exit path.
We humans cannot make all the amino acids we need in order to build proteins.
We can make some of them (e.g. tyrosine) from others (tyrosine is made by an enzyme acting on another amino acid, phenylalanine).
But we cannot make the others (e.g. phenylalanine), and they are called essential amino acids, because we have to have them in our diet.
The number of essential amino acids depends on age(children need a few more than adults, who can synthesize them) and on our genetic make-up (some diseases involve an inability to make an amino acid, which therefore is added to the essential list for that person).

When hundreds of amino acids are joined together, that results in the formation of a protein.

What type of building blocks would you use to construct a protein?
Amino acids
A Protein is a long chain of what?
A protein is a long chain of amino acids. That are linked by dehydration synthesis to form peptide bonds.
What is a subunit of protein?
amino acids
Molecules that bond together to produce a protein is what?
Amino acids are the molecules that bond together to produce a protein. Proteins are made up of chains of amino acids that are linked together through peptide bonds. The sequence of amino acids in a protein determines its unique structure and function.
Where amino acids are strung together to form a protein?
Amino acids are bonded together with peptide bonds in protein synthesis at the ribosomes.
What are the amino acids you created in your protein chain?
They are Protein Sub-Unit amino acids.
Subunit of Protein?
Amino acids
What type of building blocks would you use to construct a protein?
Amino acids
Why are amino acids call the building blocks of protein?
because protein are formed from amino acids
The order of amino acids is a protein's?
The order of amino acids in a protein determines its structure and function.
What would Hydrolysis of a protein produce?
Hydrolysis of a protein would break down the protein into its constituent amino acids. This process involves adding water to the protein molecule, causing the peptide bonds between amino acids to be cleaved, resulting in the release of individual amino acids.
What is a nutrient made up of amino acids?
Amino acids are the building blocks of proteins; hence the intake of amino acids will act nutritionally as protein.
A Protein is a long chain of what?
A protein is a long chain of amino acids. That are linked by dehydration synthesis to form peptide bonds.
Protein are polymer of?
Proteins are polymers of amino acids.
What string makes up a protein?
amino acids amino acids
What is a protein molecule made of and how many of these are there?
A protein molecule is made of amino acids linked together in a specific sequence. There are 20 common amino acids that can be used to build proteins. The number of amino acids in a protein can vary, ranging from a few dozen to thousands.
What is a protein made of?
Proteins are made up of long chains of amino acids, which are linked together by peptide bonds. Each protein has a specific sequence of amino acids that determines its unique structure and function in the body.
