Deficiency of which element in soil causes chlorosis in plants? (IFFCO 2022)

✅Explanation:
Transposable elements (TEs), also known as "jumping genes," are DNA sequences that can move around within a genome. While Ac and Tam3 are well-known transposable elements in plants, L1 elements are primarily found in animals.
-L1 Elements (LINE-1): These are a type of retrotransposon abundant in mammalian genomes. They replicate via an RNA intermediate and are involved in various genomic processes.

✏Plant TEs: Plants have their own diverse set of transposable elements, including:
-Ac/Ds System: Discovered by Barbara McClintock in maize, this system involves the Activator (Ac) and Dissociation (Ds) elements.
-Tam3: A transposon found in snapdragon (Antirrhinum majus), known for its role in flower pigmentation.
-Other Plant TEs: Plants harbor various other TEs, including retrotransposons like Ty1-copia and Ty3-gypsy, as well as DNA transposons.

📌 🔑Key Points:
-Transposable elements: Mobile DNA sequences that can move within a genome.
-Retrotransposons: TEs that replicate via an RNA intermediate.
-DNA transposons: TEs that move directly as DNA.
