When a phage comes in contact with a bacterial host, it attaches itself to the receptors at the outside surface of the cell. Once secured, the phage injects its DNA or RNA inside the cell through endocytosis. Once inside, the host will change according to the DNA or RNA injected.
For the answer to the question above, <span>Muscles can only contract, not push </span>
<span>"Muscle fiber generates tension through the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten or remain the same. Though the term 'contraction' implies shortening, when referring to the muscular system it means muscle fibers generating tension with the help of motor neurons (the terms twitch tension, twitch force, and fiber contraction are also used)."</span>
Anabolism<span> is a process in which the liver creates new proteins from digested nutrients, while </span>catabolism<span> involves the breaking down of proteins into essential amino acids. Both are vital to the body's metabolism and maintaining healthy cell function. </span>
Answer is 50.
Protein is a macromolecules and is composed of its units called amino-acids. In a protein molecule amino acids are bound together with peptide bonds to form polypeptides. Thus protein is a polypeptide. The number of amino acids in a protein molecules varies. Some polypeptides contain only 3 amino-acids, but it is not regarded as proteins due to its structural and functional differences between a simple polypeptide chain and a protein. A polypeptide of 50 amino acids is biologically functional protein that possesses all the properties of a protein. Most of the protein made of thousands of several polypeptide chains with thousands of amino-acids organised in complex structures.
