In 1953, Francis Crick and James Watson described the molecular shape of DNA as a "double helix." Double-stranded DNA is composed of two linear strands that run opposite to each other, known as ...
For anyone who has ever had experience with scientific research, it becomes evident that science is a commitment that requires ... make for their careers is Life Story: The Race for the Double Helix, ...
The backbone of the DNA double helix consists of alternating phosphate and deoxyribose sugar molecules. Interlinking bases hold the two sides together. As A is complementary to T and C is ...

(Image: National Human Genome Research Institute) The discovery of DNA and its double-helix structure was a pivotal moment in the history of genetics. In 1953, James Watson and Francis Crick proposed ...
The signature imagery of two DNA strands locked around each other is one that everyone has seen in school. And, everyone was also taught that the double helix shape with the strands are bound by ...
Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ... “This experiment is really the nail ...
More than seven decades later, mathematician Robert Monjo believes he has discovered a similarly significant double helix — but this time not as the structure of human DNA, but as the structure ...
