This means that one strand's sugar-phosphate chain runs in ... Crick were pursuing a definitive model for the stable structure of DNA inside cell nuclei. Watson and Crick ultimately used ...

Researchers in Lithuania present the molecular structure of a new, more-versatile CRISPR system for gene editing.

During cell division the two strands separate and on each strand a new "other half" is built, just like the one before. This way DNA can reproduce itself without changing its structure -- except ...

DNA stands for deoxyribonucleic acid. Nucleic acids are named for where they're found—inside the nuclei of cells—and for the ...

the helix structure is unwound special molecules break the weak hydrogen bonds between bases, which are holding the two strands together this process occurs at several locations on a DNA molecule ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double ... The double helix unwinds, and ...

The dark bands indicate areas where the structure of the chromosome is dense ... We've now zoomed in enough to see portions of the DNA strand. The DNA is wrapped around histones -- protein ...
