Following is a transcript of the video. Manny: Commercial DNA tests have been a huge trend lately. They were some of the most popular holiday gifts last year. Which makes sense, there's so much ...
For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for DNA to be the molecule that codes all life.
Not all DNA is in the double helix form described in textbooks since the 1950’s. Quadruple helix DNA, also known as G-quadruplex DNA, was identified in the human genome several decades ago, and ...
to argue that DNA actually takes the form of a double helix, a ladder-like structure that is twisted along its entire length (Figure 6). Franklin, Watson, and Crick all published articles ...
that the DNA molecule exists in the form of a three-dimensional double helix. More than 50 years passed before the significance of Miescher's discovery of nucleic acids was widely appreciated by ...
Franklin, working mostly alone, found that her x-ray diffractions showed that the "wet" form of DNA (in the higher humidity) had all the characteristics of a helix. She suspected that all DNA was ...
Except for identical twins, each person's DNA is unique. This is why people can be identified using DNA fingerprinting. DNA can be cut up and separated, which can form a 'bar code' that is ...
