Here's a lovely DNA structure from our friend, human immunodeficiency virus I. I especially like the way that two heart-like shapes appear in the structure.

Although, I didn't believe it when I first saw it. With all the years that I've heard (or taught) that all DNA is antiparallel, it was hard to believe my eyes.
Yet here is parallel DNA, with both strands oriented in the same direction, right here on your monitor. And the commenters were correct.…
How does grass grow in the extremely hot soils of Yellowstone National Park? Could a protein from a virus help plants handle global warming? Okay, that second sentence is wild speculation, but we will try to find the answer to our mystery by aligning our protein sequence to a sequence from a…
Okay, all of you biochemists and molecular biology types. I have a puzzle for you that I found by accident during a lecture. Yes, I was the one lecturing and the notes will be posted soon.
In the meantime, here's your puzzle: What's unusual about this pair of bases?

Last Friday, we had another in the series of weird DNA structures. (You can see the first here).
I asked the audience to identify the unusual feature in this molecule. Here's the first picture:

Here's the answer:
Steve L. guessed it…
DNA ?
Is this structure formed following reverse transcription of the viral RNA ?
This sequence was synthesized using phosphoramidite chemistry.
It corresponds to the cDNA sequence of the dimerization initiation site SL1 of HIV- 1(Lai) RNA.
