Example sentences for: helix

How can you use “helix” in a sentence? Here are some example sentences to help you improve your vocabulary:

It was determined very early in this methodology that the correct helix is the one that contains positions within a potential helix that vary in composition while maintaining G:C, A:U, and G:U base pairs.
In other cases, the new structure diagram reveals a possible helix in a variable region that was weakly predicted with comparative analysis.
The amino acid residues at position -1, 2, 3 and 6 of the α helix form base contacts with DNA [Reviewed in [ 49 ] ]. The amino acid sequences of the zinc finger pairs among the ZAS proteins are highly conserved [Reviewed in [ 25 ] ]. The conservation of the zinc fingers from invertebrate to vertebrate species and their common DNA binding target sequences suggest that these proteins may play similar physiological roles in diverse organisms.
Repetitive proline sequences tend to adopt a polyproline II (PPII) helix, consisting of an extended structure with three residues per turn.
A recent study identified a number of α5 helix residues in α t that when changed to alanines increased rates of guanine-nucleotide exchange ( i.e., decreased affinity for guanine-nucleotides) [ 5 ] . Individual mutation of amino acids in α t , cognate to T330, N332, V333, F337 in α i2 (Figure 1), increased nucleotide exchange rates [ 5 ] . Two of these critical amino acids, N332 and V333 in α i2 , are in fact the first two amino acids that are replaced by the novel splicing in sα i2 (Figure 1).
