Q5 | Which of the following are the advantage/s of Decision Trees?
- possible scenarios can be added
- use a white box model, if given result is provided by a model
- worst, best and expected values can be determined for different scenarios
- all of the mentioned
Q6 | Which of the given statements is incorrect about global gene regulation?
- one way to obtain useful information about a genome is to determine which genes are induced or repressed in response to a phase of the cell cycle
- sets of a gene whose expression rises and falls under the same condition are likely to have a related function
- sets of a gene whose expression rises and falls under the same condition are likely to have dissimilar functions
- cell cycle is a developmental phase, or a response to the environment
Q7 | Which of the given statements is incorrect about Microarray (or microchip) analysis?
- it is a new technology in which all of the genes of an organism are represented by oligonucleotide sequences spread out in an 80 x 80 array on microscope slides
- the oligonucleotide sequences cannot be synthesized directly on the slide
- the oligonucleotides are collectively hybridized to a labeled cdna library prepared by reverse-transcribing mrna from cells
- the amount of label binding to each oligonucleotide spot reflects the amount of mrna in the cell
Q8 | 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.

- n2
- n
- n-1
- n-4
