Fun fact: DNA sticks to plastic really easily, so it is common practice to put "carrier DNA" in biotech products that are only DNA. This carrier DNA is at a much higher concentration than your DNA of interest and fills up the plastic so the DNA we care about doesn't. Salmon sperm extract is a common carrier DNA.
Fun fact: no it does not. It sticks to glass well, but it only slightly adheres to polypropylene after spinning over 10,000g of force. That's why you add salt to DNA precipitation. Know every reagent in your protocol and why it is there.
it literally does, and here's data from Promega testing a eppendorf lo-bind tubes to oxygen tubes. https://worldwide.promega.com/-/media/files/resources/conference-proceedings/ishi-23/poster-abstracts/53-poster.pdf?rev=62368fd4fbb44e95a6d760af2b0cfa5d
