Triple Helix

Показать описание
Although the chemistry was wrong, Linus Pauling's triple-stranded DNA model was a catalyst for James Watson and Francis Crick to solve the structure of DNA.
TRANSCRIPT: This is Linus Pauling's failed attempt to predict the structure of DNA. The problem with his triple helix model is that the phosphates form the helical core, with the bases pointing outwards. This would be impossible under normal cellular conditions. Each phosphate group is negatively charged, and so many negative charges forced together would repel each other, literally driving the structure apart.

2 strand 72000 plus 72000 equals God 144000 plus a.i.72000 equals 216000 or 600×60×6 sounds so promising. Only part missing is heaven

Some say that you can go up to 12 strands not just 2 or 3.

Hi catapolt1. The animation is an accurate representation of a molecule, including Brownian motion. Thanks for the comment.

@catapolt1 Why is it shaking? Did you listen to the video at all? There are loads negative forces stuffed together in a tight spot. Shove two negative magnets together and you'll get your shaking. So thumb this video up right now!

What blood test should I take if I wanted to find out if I had a triple stranded DNA?

so does this mean a triple helix is then impossible and will never be seen?

@DNALearningCenter its accurate, but i was trying to examine its cellular structure and how the 3 strands wrap around, but for accuracy its perfect i was looking for how it looks and its constructed not its accuracy... i will thumb up
