<p>Here, <a href="https://www.youtube.com/watch?v=E9-Rm5AoZGw" rel="nofollow noreferrer">https://www.youtube.com/watch?v=E9-Rm5AoZGw</a>, ONT claims they can read non-fragmented DNA and that with the hairpin like structure the double strands can be read at once. Then why is that MinION reads are of variable in length and not the length of a whole DNA?

The MinION will read the full length of the the fragments which pass through the pore. Are you asking why it can't read the full genome in one go?

Using ONT MinION, why is that we cannot get a full length DNA read?
