#1
Front (Question)

There are four levels of structure in proteins, three are related to a single polypeptide chain and the fourth level relates to a protein that has two or more polypeptide chains Polypeptide or protein molecules can have anywhere from 3 amino acids (Glutathione) to more than 34,000 amino acids (Titan) bonded together in chains

Back (Answer)

#2
Front (Question)

What is the primary structure of a protein

Back (Answer)

The sequence of amino acids bonded by covalent peptide bonds is the primary structure of a protein

#3
Front (Question)

What determines the primary structure of a protein and how does differed the proteins primary structure this affect

Back (Answer)

DNA of a cell determines the primary structure of a protein by instructing the cell to add certain amino acids in specific quantities in a certain sequence. This affects the shape and therefore the function of the protein

#4
Front (Question)

How many amino acids in living organisms

Back (Answer)

How many amino acids in living organisms

#5
Front (Question)

What is a protein

Back (Answer)

Proteins are made up of repeated units of amino acids which link with each other via peptide bonds
