Options are not provided in the question. The complete question is as following:
A researcher has performed a BLASTp search for a protein of interest. He identifies a globular protein that shares 30 percent of its amino acid sequence and positioning with his target protein. What can he conclude about the shape of his protein of interest?
a) It is also a globular protein.
b) It is a fibrous protein.
c) It has only a primary structure.
d) It demonstrates only pleated sheets as part of its structure.
e) The researcher can conclude nothing about his protein of interest.
Answer:
a) It is also a globular protein.
Explanation:
Globular proteins are one of the common form of protein (the other are fibrous, disordered, and membrane proteins) having spherical shape.
Protein-protein BLAST (blastp), This software returns the most related sequences of protein from the protein database defined by the user, provided a protein query.
So, the blastp has searched for globular protein.
Hence, the correct option is a.
