Hand-foot-and-mouth disease is an illness that causes sores in or on the mouth and on the hands, feet, and sometimes the buttocks and legs. The sores may be painful. The illness usually doesn't last more than a week or so. Hand-foot-and-mouth disease is common in children but can also occur in adults. It can occur at any time of year but is most common in the summer and fall.
In fact, each gene in cellular DNA contains the code for a unique protein structure. Not only are these proteins assembled with different amino acid sequences, but they also are held together by different bonds and folded into a variety of three-dimensional structures.he linear sequence of amino acids within a protein is considered the primary structure of the protein. Proteins are built from a set of only twenty amino acids, each of which has a unique side chain.
Best Answer: Levels of Protein structure: 1. Primary: refers to the unique sequence of amino acids in the protein. All proteins have a special sequence of amino acids, this sequence is derived from the cell's DNA. 2. Secondary: the coiling or bending of the polypeptide into sheets is referred to the proteins secondary structure. alpha helix or a beta pleated sheet are the basic forms of this level. They can exist separately or jointly in a protein.
