Which of the given statement is incorrect about the gene map?


aGene order in two related organisms reflects the order that was present in a common ancestor genome. Chromosomal breaks followed by reassembly of fragments in a different order can produce new gene maps

✖


b Gene order is only revealed by the physical order of genes on the chromosome

✓


cSequence variations (polymorphisms) that are close to (tightly linked) a trait may be used to trace the trait by virtue of the fact that the polymorphism and the trait are seldom separated from one generation to the next

✖


dThese types of evolutionary changes in genomes have been modeled by computational methods

✖



Which of the given statement is incorrect about Functional Genomics?


aFunctional genomics involves the preparation of mutant or transgenic organisms with a mutant form of a particular gene usually designed to prevent expression of the gene

✖


b An abnormal properties of the mutant organism does not reveal the gene function

✓


cWhen two or more members of a gene family are found, rather than a single match to a known gene, the biological activity of these members may be analyzed by functional genomics to look for diversification of function in the family

✖


dA more detailed analysis of the relative amount of sequence variability in a chromosomal region within populations of closely related species can reveal the presence of genes that are under selection

✖



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

✖


bWhich genes are expressed at a particular stage of developmental cycle of an organism

✖


cWhich genes are depleted at what time

✓


dGenes that respond to a given environmental signal to the same extent
