Question

Given below are two statements :
Statement (I) : Insertion Sequences (IS) are short DNA sequences (800-1400 bp) and have the ability to transpose.
Statement (II) : IS also promotes recombination between non-homologous chromosomes.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

IS elements are simple transposable bacterial elements (800–1400 bp) encoding only transposase. Because they are present in multiple identical copies, they act as portable regions of homology, facilitating chromosomal crossovers and rearrangements.

Answer 1

The Correct Option is A
