Explanation:
The mitochondria are membrane-bound cellular organelles found in the cell of an eukaryote. Mitochondrion is responsible for the production of energy since the process which releases the energy (cellular respiration) occurs in it.

Answer: The lagging strand glows more because its RNA primer is nearer the replication fork.
During DNA replication process, both the strands of DNA are replicated simultaneously in opposite direction. One strand is replicated continuously and known as leading strand while the other strand is replicated discontinuously and known as lagging strand. The leading strand has only one primer attached to it while the lagging strand
