It is how DNA works in the case of PCR, for example. The denaturation cycle splits double stranded DNA into individual single strands, which can be thousands of base pairs long. Primers are short sequences that bind to these single strands. If there are only one or two mismatches, the primer can easily bind to the wrong part of the DNA strand, if the temperature during the annealing step is low enough. This causes messy gels and incorrect DNA products in the PCR.

In some cases, if the temperature is very low, the primer can bind to sequences with many mismatches. This results in the scientist crying and finding god.

Nice fungus

Plus I just looked at the price. I also have a Ninja - $90. Vitamix - $600. I’d have to be blending a whole lot to shell out that much, but I’m not, so I didn’t. The Ninja works great and is the best blender I’ve used so far, so I don’t see a reason to upgrade. Use what works for you!

Gotta cook those bad boys within a few hours, otherwise they start to ink up (not the best not the worst, still edible). Some people even let them completely turn into goo for specific recipes.

Nope, that is a Coprinus comatus lookalike - Coprinopsis atramentaria. You don’t want to consume alcohol within a few days of eating that mushroom, before or after.
