Example sentences for: orthologous

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

  • The sequences were compared with the sequences of subclones of the genomic BDNF clone c241 which we had previously identified and partially sequenced [ 27 ] . Five of the ten sequenced 5' RACE clones contained the already known and previously cloned 5' exon [ 4 ] . This exon was named exon 1c because it contains a 39 nucleotide segment in which 37 nucleotides are identical with a segment in rat exon III, suggesting the two exons are orthologous (see table 1 and figure 2a) [ 25 ] .

  • Probably the most obvious of such characteristics is the presence-absence of representatives of the analyzed species in orthologous groups of genes, and recently, at least three groups have employed this approach to build genome trees, primarily for prokaryotes [ 8 9 10 ] . An alternative way to construct a genome tree involves using the mean or median level of similarity among all detectable pairs of orthologs as the measure of the evolutionary distance between species [ 11 ] . Yet another possibility involves building species trees by comparing gene orders.

  • This prediction was tested by evaluating the branch lengths estimated from alignments of orthologous protein sets of the three species groups.

  • The substitution rates for orthologous gene pairs were calculated using the same approach.

  • The use of the orthologous comparisons with a lower K s , and thus with potentially stronger selection in the synonymous sites, could, in principle, bias our comparison of the K n /K s ratio.
