  • A single dna molecule is too small to see with the naked eye, but a few million dna molecules released from a few million microbes is easy to see IRL. In my bio lab days we did an experiment to isolate the dna molecules from a scoop of microbes, and at the end you wind up with a clump of dna molecules that together are about the size of an eraser head.

    And yeah as the other person said, the term “staining” is the official term used for what you’re calling “tagging”













  • There’s a map that shows where every file on your disk is. Doing a regular trash just erases the map pointer for that file, but the 1s and 0s that the file is made of are still sitting there on your disk. Secure erase writes 0s into that area on the disk, so even if you knew where that file used to be located on the disk, now you’ll just find 0s there, instead of finding the 1s and 0s of the old file.
