    Correct Answer: D

    Solution :

    Jumping genes (trarisposons ortransposable elements) are mobile genetic elements, which move from one place to other in the chromosome. These were first discovered by Barbara McClintock in maize. Exon is a sequence of nucleotides (Cistron) that remain active after processing of m-RNA in eukaryotes and translated for protein, Introns are sequence of nucleotides on pre m-RNA, which are not translated and removed during processing in eukaryotes. The particles (granules or mass) which present in cytoplasm are called, cytoplasmic particles.
