Words similar to contrast
Example sentences for: contrast
How can you use “contrast” in a sentence? Here are some example sentences to help you improve your vocabulary:
In contrast, computational studies have suggested that the purpose of such a network is to achieve extreme positive cooperativity, so that the pathway behaves in a switch-like, rather than a graded, fashion (Huang and Ferrell 1996).
In contrast, tra and dsx are key sex regulators in all dipterans examined thus far.
The RDRPs of RNA viruses define one major lineage of nucleic acid polymerases, which additionally includes reverse transcriptases, archaeo-eukaryotic DNA polymerases, and nucleotide cyclases [ 8 9 10 11 12 13 ] . The DNA-dependent RNA polymerase of certain bacteriophages, such as T7, and the archaeo-eukaryotic primase (also detected in some bacteria) are divergent derivatives of the same fold [ 11 14 ] . The core catalytic domain of all these enzymes, the so-called "palm" domain, has an RNA-recognition motif (RRM)-like fold with strategically placed metal-coordinating residues, which form the active site [ 11 15 16 ] . In contrast, bacterial DnaG-type primases (also present in archaea and some eukaryotes) contain a polymerase domain of the Rossmann-like TOPRIM fold, which is shared with topoisomerases and OLD-family nucleases [ 17 18 19 ] . The recently solved structures of the DDRPs from yeast and the thermophilic bacterium Thermus thermophilus indicate that the β' subunit (according to the subunit nomenclature of Escherichia coli DDRP, which we hereinafter employ to designate all orthologs of the respective E. coli subunits) of these enzymes defines another distinct catalytic scaffold, which is unrelated to any of the above template-dependent RNA polymerases [ 20 21 22 23 24 ] . Additionally, the structural and evolutionary affinities of two other template-dependent RNA polymerases, namely RDRPs involved in PTGS [ 25 26 27 ] and primases of herpesviruses [ 28 ] , remain obscure.
Evaluation was performed on a Leitz DM RB (Leica Inc., Wetzlar, Germany) microscope equipped with differential interference contrast and a DEI-470 CCD Video Camera System (Optronics Engineering, Goleta, CA) with detail enhancement.
The HR occurs in response to infection with avirulent bacteria at levels of inoculum that cause a large percentage of leaf cells to undergo programmed cell death (PCD) [ 8 ] . In contrast to results with avrRpt2, P. syringae bacteria carrying the avirulence genes avrB , avrRpm1 , avrPphB or avrRps4 elicit an exaggerated HR relative to that on the wild-type Columbia parent [ 5 7 ] . In a study in which bacteria carrying avrB were chosen as a representative member of this class, in further contrast to results with avrRpt2 , these bacteria were capable of eliciting SAR and PR-1 induction on ndr1-1 mutant plants [ 4 ] .
