1.

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

A. Gene 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
C. Sequence 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
D. These types of evolutionary changes in genomes have been modeled by computational methods
Answer» C. Sequence 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

Which of the given statement is incorrect about Functional Genomics?

A. Functional 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
C. When 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
D. A 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
Answer» C. When 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
