Question

Given below is a sequence of alphabets representing the genes of chromosome. Observe it and answer the questions.

A-B-C-D-E-F-G-H-I-J-K.

(a) Write the sequence of genes after the chromosome undergoes terminal deletion of single gene.

(b) What will be the gene sequence, if the genes E and F undergoes tandem duplication? 

(c) Consider the centromere is located between the genes F and G and write a gene sequence, after paracentric inversion occurs in between the genes C, D and E.

Answer 1

(b) A – B – C – D – E – F – E – F – G – H – I – J – K.

(c) A – B – E – D – C – F – G – H -1 – J – K.
