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 ...

these strands twist together to form a double helix. The structure of DNA can also be described as a ladder. The chemical backbones of the ladder are made up of sugar and phosphate molecules that ...

The Double Helix” paints Watson and Crick as lone pioneers while downplaying the contributions of others, most notably of ...

This DNA ladder is about 2 meters long but only 2 nanometers wide, and it’s all packed into a tiny ball (nucleus) about 5 micrometers in diameter. To put this into perspective, imagine a 3,100 ...
