Franklin interpreted them as representing distances between the nucleotides that were arranged in a spiral shape called a helix ... string. It is impossible for researchers to see double-stranded ...

In other words, a piece of DNA that is 1 meter long will become a "string-of-beads" chromatin fiber just 14 centimeters (about 6 inches) long. Despite this shortening, a half-foot of chromatin is ...

Here is a view of the double helix -- the subject of Rosalind ... The sides of the DNA ladder consist of a long string of sugar and phosphate molecules, to which the bases are attached.

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...

This showed that DNA had a helix shape. Without her knowledge, one of her colleagues showed the picture to James Watson. When he saw it, he knew that his and Francis Crick’s theory about the ...

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 ...
