Question

Which of the following information is not directly obtained by microarray analysis?

(a) Which genes are expressed at a particular stage of the cell cycle

(b) Which genes are expressed at a particular stage of developmental cycle of an organism

(c) Which genes are depleted at what time

(d) Genes that respond to a given environmental signal to the same extent

I got this question in an online interview.

My doubt is from Sequence Assembly and Gene Identification topic in chapter Collecting & Storing Sequences in Laboratory of Bioinformatics

Answer 1

Right choice is (c) Which genes are depleted at what time

To explain: For chronological information there are other numerous techniques that can be followed. This type of information provides an indication as to which genes share a related biological function or may act in the same biochemical pathway and may thereby give clues that will assist in gene identification.
