Example sentences for: covariation
How can you use “covariation” in a sentence? Here are some example sentences to help you improve your vocabulary:
Pairwise covariation of 3:1 dinucleotide frequencies was assessed by the Spearman rank correlation coefficient [ 45], a nonparametric rank statistic for testing monotonic relationships.
Approximately 8500 16S and 16S-like rRNA sequences and 1050 23S and 23S-like rRNA sequences were collected from all branches of the phylogenetic tree, as shown in Section 2, "Nucleotide Frequency and Conservation Information" and in Table 2. These sequences have been aligned and analyzed with several covariation algorithms, as described in more detail in the "Predicting RNA Structure with Comparative Methods" section of the CRW Site http://www.rna.icmb.utexas.edu/METHODS/and in Section 2A.
This value increases to the maximum score as the percentage and the amount of pure covariations (simultaneous changes at both positions) increase in parallel with a decrease in the number of single uncompensated changes, and the number of times these coordinated variations occur during the evolution of that RNA (for the rRNAs, the number of times this covariation occurs in the phylogenetic tree) increases.
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).
Proposed base pairs were taken out of the structure model when the number of sequences without either a covariation or a G:C, A:U, or G:U base pair was greater than our allowed minimum threshold; the nucleotide frequencies for those base pairs are available from the "Lousy Base-Pair" tables that are discussed in the next section.
