| Alternatively, changes in tilt or roll angles may change the direction of the helix axis, giving rise to axial flexibility. |
| Even the codiscoverer of the DNA double helix, Sir Francis Crick, displayed humility that is totally lacking in the present day know-alls. |
| After ascending the helix of stairs, I sat down at my computer and pulled up the logs that Marius had sent me. |
| The one strand of RNA is annealed with its complementary strand of DNA, which causes the other strand of DNA to be displaced from the helix. |
| The DNA structure is a double helix looking something like a twisted ladder. |
| If tilt is assumed to be the sole cause, the C-terminal helix of the peptide would need to be at a 300 angle with respect to the bilayer normal. |
