Answer:
Topogenic sequences share a series of structural features, and thereby computational algorithms can be used to predict these protein-membrane segments
Explanation:
Topogenic sequences are protein segments formed by alpha-helical transmembrane domains, which are required for the insertion of membrane proteins. These domains share a series of well-defined features: they are composed of segments of about 20 hydrophobic amino-acid residues. In consequence, computational algorithms can be designed to identify protein patterns that fulfill these structural requirements (i.e. segments with a length of 20 residues, hydrophobic level, etc). The models assign a similarity threshold (threshold value) that predict if the similarity level of the protein pattern is good enough to detect a topogenic segment.

The answer is B. It is the only one where each element has the same number of molecules on each side.
Covalent bonds are formed when two non metal atoms share an electron. The atoms either give up or gain an electron, due to the outer shell being unstable.
