1.	If the two sequences share significant similarity, it is extremely ______ that the extensive similarity between the two sequences has been acquired randomly, meaning that the two sequences must have derived from a common evolutionary origin.(a) unlikely(b) possible(c) likely(d) relevant
Answer» Right answer is (a) unlikely To explain I would say: Sequence alignment provides inference for the relatedness of two sequences under study. Regions that are aligned but not identical represent residue substitutions; regions which residues from one sequence correspond to nothing in the other represent insertions or deletions that have taken place on one of the sequences during evolution.

Which of the following is untrue about SCOP?(a) It is a database for comparing and classifying protein structures(b) It is constructed almost entirely based on manual examination of protein structures(c) The proteins are grouped into hierarchies of classes, folds, superfamilies, and families(d) The SCOP families consist of proteins having low sequence identity (>30%)
Which of the following statements about SCOP is incorrect regarding its features?(a) Proteins with the same shapes but having little sequence or functional similarity are placed in different super families, and are assumed to have only a very distant common ancestor(b) Proteins having the same shape and some similarity of sequence and/or function are placed in ‘families’, and are assumed to have a closer common ancestor(c) SCOP was created in 1994 in the Centre of Protein Engineering and the University College London(d) It aims to determine the evolutionary relationship between proteins
