DNA and RNA Nucleotide Structure and Mnemonics Video

I've been planning to do a video about DNA and RNA nucleotide mnemonics for quite a while. I finally got around to making that video. I think I have a unique take on the mnemonics at least that may be helpful for some people. Hopefully this will make up for all the other goofy/useless videos I've been posting... I need to get something for my mic that makes it so it doesn't amplify my breathing so bad. Also, I need to say "umm" less, and instead of making half-under-my-breath asides, I should just say those things loudly like everything else. Other than that, I think it's a good video.

In summary:
The nucleotide mnemonic I use is:
GACT. I like it because it's goofy sounding, so it's easy to remember. The purines are before the pyrimidines (just like purine comes first in the dictionary). you can rearrange it like so:
GA
CT
to remember that G binds to C and A binds to T. GC bonds are stronger than AT bonds. So that pair comes first.

for RNA, it becomes GACU (pronounced: "Gackoo"). Everything about GACT is also true about GACU. If you can remember both, you will easily be able to remember that U replaces T in RNA.

My other shaver is a double-edged razor blade duct-taped to a trowel

Even though I only shave a few times a year, I consider myself somewhat of a shaving enthusiast. I've tried straight razors, and double edged razors, and electric razors, and whatever the heck you call the things Gillette is selling these days.

What I've learned is that you don't really need anything special to get a decent shave. All you really need is a really sharp blade mounted firmly on a handle (some quality shaving soap also really helps). To prove that point, I decided to cut my big beard off with a razor blade duct-taped to a trowel!  Read on for details (and a 7.5 minute video of the act itself).

Learning about DNA topology by playing with string

The only way I was ever able to get any kind of intuitive feel for DNA topology was to play with string, twisting it, wrapping it, untwisting it etc.
I made a video demonstrating some ways model DNA structures with string, so grab some string and follow along!

(also my first foray into youtube, I'm not sure if or when I'll ever post anything else there though, but I think this turned out ok)
