Question

The stretches of DNA that can jump within the genome, are named as:

• A. Satellite DNA
• B. Transposable elements
• C. Introns
• D. Exons

Hint:

Remember that transposons can 'jump' around the genome.

Answer 1

The Correct Option is B

Step 1: Concept
Transposon

Step 2: Meaning
A segment of DNA that can change its position within the genome without causing cell death. These segments are capable of 'jumping' or moving from one location to another in the genome.

Step 3: Analysis
Satellite DNA refers to highly repetitive sequences at the centromeres and other regions of chromosomes, not transposable elements. Introns and exons refer to coding regions within genes; they do not move within the genome.

Step 4: Conclusion
Transposable elements are capable of moving from one location to another in the genome, which matches the description given in the question. Final Answer: (B)
