Answer:
DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. If the two DNA profiles are a match, then the evidence came from that suspect.

Maximum Thrift is a method / philosophy that considers the shortest tree (in number of transformation steps) the best hypothesis about the phylogenetic relationship of a given set of terminals. Transformation step is the cost attributed to the change of character state in a given branch of the tree, be it the change from one nucleotide base to another, amino acids, or the color of an animal's iris. The fewer transformations, the shorter the tree, and therefore the more parsimonious. In this method, what programs do is to investigate as many alternative topologies as possible (or all if their array has less than 25 terminals; see more details below) given their character array. Each will be measured, and the shorter (optimal) trees will be retained as the most parsimonious result.
Proteins. <span>The amino acids in a polypeptide chain are linked by peptide bonds. Once linked in the </span>protein<span> chain, an individual amino acid is called a residue, and the linked series of carbon, nitrogen, and oxygen atoms are known as the main chain or </span>protein<span> backbone.</span>

Explanation:
Each molecule has a characteristic size and shape that determines its function in the living cell. The shapes of molecules are determined by the positions of the atoms' orbitals. When an atom forms covalent bonds, the orbitals in its valence shell are rearranged.
<span>Atoms that have filled outermost energy levels and do not participate in chemical bonding are called Inert Atoms. Remember this by thinking of the definition of Inert; meaning unable or not having the strength to move. So if it an atom has a filled outer level the electrons will be inert.
