Question
Biology Question on recombinant technology
Closely linked genes can be separated by
A
recombination
B
inversion
C
deletion
D
translocation
Answer
translocation
Explanation
Solution
Two closely linked genes are located at a very small distance on a chromosome. Recombination cannot easily separate them. During inversion, sequence of genes on a chromosome is inversed thus the linked genes will not be separated but their positions will be changed. Deletion will completely remove a gene, it cannot be termed separation. Translocation is the condition in which section of a chromosome is broken off and is attached to another. This may result in separation of two linked genes.
