Vedclass · Answer

(A) The original gene sequence is $P-Q-R-S-T-U-V-W$.According to the diagram,the chromosome breaks between $Q$ and $R$,and between $U$ and $V$.The segment between these break points is $R-S-T-U$.In an inversion mutation,this segment is rotated by $180^{\circ}$,reversing its order to $U-T-S-R$.Therefore,the new gene sequence becomes $P-Q-U-T-S-R-V-W$.

The chromosome shown in the diagram below is broken at the points which are indicated by the arrows and the genes between these points become inverted. The resulting order of the genes will be:
