Question: 137: Transposons can be used during which one of the following ?
(1) Autoradiography
(2) Gene sequencing
(3) Polymerase Chain Reaction
(4) Gene SilencingTransposons can be used during which one of the following ?
Answer: Option (4)
Explanation:
Transposons are mobile genetic elements that can move from one position to another within the genome.
They can disrupt gene expression when they insert into or near a gene.
This property of transposons is used in gene silencing, where insertion of a transposon can inactivate or suppress the expression of a target gene.
Gene silencing is an important tool in functional genomics to study gene function.
Autoradiography is used to detect radioactive molecules and does not involve transposons.
Gene sequencing determines the nucleotide order in DNA and does not require transposons.
Polymerase Chain Reaction is used for DNA amplification and also does not involve transposons.
Therefore, transposons are used during gene silencing, making Option (4) correct.
