Question 2

Describe the DNA helix proposed by Watson and Crick.

Accepted Answer

The DNA model proposed by Watson and Crick contains two DNA polymer strands coiled around a common axis. The strands are oriented in opposite directions, from 5` to 3` (antiparallel), and the two strands are twisted in a right-handed coil. The sugar-phosphate backbone is located on the outside. The base pairs are stacked in the center of the helix and are stabilized by specific hydrogen bonds between AT and GC base pairs. The base pairs lie perpendicular to the axis, with10 base pairs per turn. The helical structure repeats every 34 Å.
