(1) The gray bands indicate the helix regions of the protein.

(2) It described his proposal for a different type of helical structure, which he called the helix .

(3) The ear print on the safe had a circular mark at the top of the ear helix .

(4) Although Concrete art is typically austerely geometrical, it is not necessarily so; Bill's sculpture, for example, often uses graceful spiral or helix shapes.

(5) The crucial trick is that the helix is not even: it has a significantly larger diameter in the middle than at the ends.

(6) DNA molecules in nature are built from two complementary strands that bind to form the double helix .

(7) The double helix of DNA is held together by hydrogen bonds.

(8) A template in the shape of a narrow right-angle triangle is wrapped around the cylinder to be threaded, and the hypotenuse of the triangle forms the line of the helix .

(9) Decrease oxygen saturation in blood in the helix of the ear by using an ear oximeter.

(10) They found that DNA consists of two connected twisted strands in the shape of a helix .

(11) Terrified, he ran to a stairwell; its helix curved upward toward the floors above.

(12) Ross Lovegrove's stairway, with its helix profile, is part of a new tendency by designers to borrow forms from nature.

(13) It turns out that a helix , essentially, is a great way to bunch up a very long molecule, such as DNA, in a crowded place, such as a cell.

(14) A television monitor showed what was inside: a glowing ball of gas surrounded by a metal helix .

(15) The conical helix of their upward spiral against the flat blue sky is completely hypnotic.

(16) The building blocks are chosen so that the ribbon curls into a helix .

(17) He was looking at the picture of the helix .

(18) Part of the gene was not arranged in the double helix structure, they noticed.

(19) The excess is carefully cut away to fabricate the helix shape.

(20) Seven of the predicted helices in our final structure are consistent with the model of MacDonald.
