While resolution of CLIP-seq is generally limited to ∼30 60 nt [ 78] based on the length of the cross-linked RNA molecules after fragmentation, digestion of the cross-linked protein leaves an amino acid 'tag' on the RNA sequence, which can occasionally cause the reverse transcriptase to skip or misread the cross-linked base, producing mutations that can be diagnostic of the binding site [ 78].
But occasionally the positions reverse, as they might just do for Jiri Bubenicek, a Czech choreographer whose new work for the New York City Ballet opens at the company's spring gala on May 13.
Although the virtual reads were generated on the forward strand, reads were occasionally aligned on the reverse strand, indicating multialigned sequences on opposite strands.
Occasionally the trend would reverse itself sharply, such as during the Persian Gulf War or whenever Michael Jordan was leading the Bulls through the playoffs to an NBA championship.
By studying ancient magnetic fields locked in the metallic grains of volcanic rocks and sediments, geologists know that the field occasionally reverses: The north magnetic pole becomes the south, and vice versa.
The last of the Time Lords, Doctor Who, uses his Time And Relative Dimension In Space – much bigger, of course, than it appears from the outside – to travel through the universe and time saving planets and civilisations and, occasionally, to "reverse the polarity of the neutron flow".
Being built over the old Briar Hill layout, some of the new holes would use the same imprint, he said, but the holes will not run in any similar order and will occasionally even run in the reverse direction.
But occasionally the tempos are reversed, especially in scenes of the Ambassador staff tearing around the bowels of the hotel like frenzied, hyperactive little robots.
Occasionally the first horse reversed into the second using a threat to kick.
Although the phylogenetic tree method often succeeds where RSD fails, the reverse could occasionally be true.
