The statement "To see DNA without a microscope, many strands must be clumped together" relates to the visibility of DNA in a similar way to how many threads become more visible when woven together. Just as individual cotton threads are difficult to see from a distance but become more noticeable when they are grouped together, individual DNA strands are too small to be seen without a microscope. However, when many DNA strands are concentrated together (for example, during extraction), they can form a visible mass that can be seen with the naked eye.
