Question

Sets of proteins that are part of stable complexes and sets of proteins involved in transient interactions ____ in terms of the similarity in gene expression among the set of proteins.

(a) are similar

(b) differ

(c) are same

(d) show similar function

Answer 1

Correct option is (b) differ

For explanation: Proteins permanently associated in a stable complex need to be present or absent in the cell at the same time. Analysis of microarray data by Gerstein and co-workers by methods along the lines, has shown that the members of stable complexes in the yeast Saccharomyces cerevisiae have highly correlated gene expression patterns.
