Q. The designation ECa.b.c.d conveys information. Which of the following is not one of it?

View solution

Q. An approach to classification of genes that encode enzymes is to examine relationships among multiple enzymes that perform the same biochemical function in the same organism.

View solution

Q. Other functional classification schemes for genes include a broader category for genes involved in the same biological process, e.g., a three-group scheme for energy-related, information-related, and communication-related genes has also been used.

Q. Which of the given statements is incorrect about Microarray (or microchip) analysis?

View solution

Q. Once a set of genes that are co-regulated has been found, the promoter regions of these genes may be analyzed for conserved patterns that represent sites of interaction with specific transcription factors.

Q. Which of the given statements is incorrect about Microarray Analysis?

View solution

Q. In cluster analysis of microarray data– If Xi is the log odds value for gene X at time i, then for two genes X and Y and N observations, a similarity score is calculated. S(X,Y) is also known as the Pearson correlation coefficent. Xoffset and Yoffset can be the mean of the observations on X or Y, respectively, in which case is the standard deviation, or else Xoffset and Yoffset can be set to zero when a reference state is used. Which of the following best represents it?

View solution

Q. In cluster analysis of microarray data– A node is created between the _________ scoring pair, and the gene expressed profiles of these two genes are averaged and the joined elements are weighted by the _________ of elements they contain.

View solution

Q. In cluster analysis of microarray data– For n genes, the process is repeated ________ times until a single element remains.

View solution

Q. The hierarchical clustering method generates a similarity score [S(X,Y)] for all gene combinations, places the scores in a matrix, joins those genes that have the highest score, and then continues to join progressively less similar pairs.
