Sentence examples for both size and sequence from inspiring English sources
Telomerase RNAs are notoriously difficult to find, as they are highly divergent among different species, varying in both size and sequence composition [ 7, 73].
The lack of conservation in both size and sequence of the central portion of the TACC3 proteins of human and mouse has been previously noted, and accounts for the major difference between these two orthologues [ 2].
The C-terminal domains of both PE and PPE protein families are highly variable in both size and sequence and often contain repetitive DNA sequences that differ in copy number between genes [ 1].
The observation that many introns harbor conserved sites under purifying selection is now commonplace, and several studies have found evidence for adaptive evolution in variation segregating within introns (Parsch et al. 2010; Hayden et al. 2011; Cagliani et al. 2012), suggesting that both size and sequence may be shaped by non-neutral forces.
Both the size and sequence of the PCR products confirmed the duplication.
Interestingly, virB6- 4 R3 and R4 were identical both in size and sequence in the Dog1 and rodent strains despite differing markedly from the HZ and Dog2 strain regions (Additional file 2: Figure S2A).
The NCRs of the three human lice vary substantially in both size and nucleotide sequence.
Within this 400 bp region, which still remains intact in T. vaginalis Tor-A and Casu2, an alternative start codon is present, which results in an extension of TVAG_243730 in T. vaginalis Tor-A and Casu2, which resemble the P. harei ortholog with respect to both size and nucleotide sequence similarity.
Given the nucleotide level identity between B. licheniformis NCIMB-8874 pre-comX and B. subtilis Ro-E-2 is only 31%, we postulate that the ComX pheromone amino acid residue in these two strains varies substantially both in size and sequence.
In all cases, the amplification efficiencies were greater than 90% and both amplicon size and sequence were confirmed.
Further sequencing of the putative ori region of an additional 37 Wolbachia strains from diverse hosts confirmed the overall characteristics of this region both in size and sequence [see Figure 1 and Additional Table 1].
