Example sentences for: covariation-based

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

  • An analysis of these tables reveals several major conclusions from the evolution of the 16S and 23S rRNA covariation-based structure models.

  • Base triples are interactions between a base pair and a third unpaired nucleotide; base triple frequencies are provided for a) base triples in the current covariation-based structure models and b) tentative base triples predicted with covariation analysis.

  • Our objective is to categorize the improvements in these covariation-based comparative structure models by tabulating the presence or absence of every proposed base pair in each version of the 16S and 23S rRNA structure models, starting with our first 16S [ 15 ] and 23S [ 19 ] rRNA models.

  • Base pair frequencies are presented for a) all base pairs in the current covariation-based structure models, b) tentative base pairs predicted with covariation analysis, and c) base pairs previously proposed with comparative analysis that are not included in our current structure models due to a lack of comparative support from the analysis with our best covariation methods on our current alignments (named "Lousy" base pairs).

  • Recently, we utilized this system to identify and quantitate the following biases for adenosines in the Bacterial 16S and 23S rRNA covariation-based structure models [ 63 ] : 1) approximately 2/3 of the adenosines are unpaired; 2) more than 50% of the 3' ends of loops in the 16S and 23S rRNA have an A; 3) there is a bias for adenosines to be adjacent to other adenosines (66% of these are at two unpaired positions, and 15% of these are at paired/unpaired junctions); and 4) the majority of the As at the 3' end of loops are adjacent to a paired G. These results were discerned with this system and are shown in part in Figure 5and H-4C.
