Biology Question on the molecular basis of inheritance
Transposons can be used during which one of the following?
A
Polymerase chain reaction
B
Gene silencing
C
Autoradiography
D
Gene sequencing
Answer
Gene sequencing
Explanation
Solution
Transposable elements, also known as transposons or jumping genes, are segments of DNA that can relocate themselves within a genome. Currently, transposons are being utilized to enable efficient and precise large-scale DNA sequencing. To sequence a genome using a transposon-based approach, large clones are fragmented into smaller, overlapping clones that are then subjected to transposon mutagenesis.
