Verified step by step guidance

Understand the concept of transposable elements: Transposable elements, also known as 'jumping genes', are DNA sequences that can change their position within the genome. They play a significant role in genetic variation and evolution.

Identify the transposable elements in Drosophila: In the fruit fly Drosophila, the most well-known transposable element is the P element. It is a DNA transposon that can move within the genome and is often used in genetic research.

Differentiate between the given options: The Ds element and Ac element are transposable elements found in maize, not Drosophila. The Alu element is a transposable element found in humans, specifically a type of SINE (Short Interspersed Nuclear Element).

Recognize the correct transposable element for Drosophila: Based on the options provided, the P element is the correct transposable element associated with Drosophila.

Conclude with the identification: The P element is the transposable element in Drosophila, distinguishing it from the other elements listed, which are associated with different organisms.
