Internucleosomal DNA cleavage yields a ladder pattern in electrophoretic gel, which is a biochemical hallmark of apoptosis (see part b of the figure for an image of a DNA electrophoretic gel with ...

The double-stranded DNA that results from this pattern of bonding looks much like a ladder with sugar-phosphate side supports and base-pair rungs. Note that because the two polynucleotides that ...

DNA, which stands for deoxyribonucleic acid, resembles a long, spiraling ladder. It consists of just a few kinds of atoms: carbon, hydrogen, oxygen, nitrogen, and phosphorus. Combinations of these ...

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