Question

In the provided agarose gel electrophoresis image, what is represented in lane 1 compared to lanes 2 through 4?

विकल्प

• Lane 1 contains fully digested fragments, while lanes 2 to 4 contain intact circular plasmids

• Lane 1 contains purified primers, while lanes 2 to 4 contain Taq polymerase

• Lane 1 contains positively charged proteins, while lanes 2 to 4 contain RNA transcripts

• Lane 1 contains undigested DNA, while lanes 2 to 4 contain digested sets of DNA fragments

Answer 1

In a typical agarose gel electrophoresis run, lane 1 displays the migration of undigested DNA, whereas lanes 2 through 4 display distinct bands resulting from the digestion of DNA fragments into various sizes.
