MCQ on Transposons (Jumping Genes)







Transposons, also known as “jumping genes,” are DNA sequences in the genome that can move or “transpose” to different locations within the genome. They can disrupt genes, cause mutations, or regulate gene expression. Transposons play a role in evolution and genetic diversity but can also lead to genetic disorders if they disrupt crucial genes. This MCQ on Transposons will help you to study the structure of transposons.

The presence of transposons can lead to genome instability due to their ability to cause:

Some transposons carry genes that encode enzymes required for their own transposition. What are these enzymes called?

Transposons can be classified into two main types based on their transposition mechanism. What are these types?

Retrotransposons use an RNA intermediate during transposition. What enzyme is responsible for the reverse transcription of RNA into DNA?

DNA transposons move directly as DNA sequences and use transposase to cut and paste into the genome. Which of the following is a well-known DNA transposon in maize (corn)?
