Question

Transposons are:

• A. Housekeeping genes
• B. Jumping genes
• C. Transporting genes
• D. Stationary genes

Answer 1

The Correct Option is B

Transposons, also known as "jumping genes", are segments of DNA that have the ability to move or "jump" from one location to another within the genome. They can integrate into different parts of the genome, which may result in mutations or changes in gene expression. This ability to move is why they are often referred to as jumping genes.

Here’s the breakdown of the other options:

(1) Housekeeping genes: These are genes that are essential for the basic functioning of the cell and are typically expressed in all cells. They are not related to transposons.

(3) Transporting genes: This term does not accurately describe transposons. While transposons "move," they do not "transport" genes in the traditional sense.

(4) Stationary genes: This term is not relevant to transposons. Transposons are defined by their ability to move, not by being stationary.

Thus, the correct answer is (2) Jumping genes.

Answer 2

Transposons, also known as "jumping genes," are DNA sequences that can change positions within the genome, which can cause mutations or alter genome size. This mobility distinguishes them from other genes, allowing them to impact genetic variation.
