Meanings
- not comparablemolecular biologybiologyCharacteristic of a structure composed of sigma bonds.
agents which stimulate transcription suggest that sigmalike factors also exist for the eukaryotic polymerases.
2013, Harry Harris (editor), Advances in Human Genetics, page 2912 more examples
This is at least defensible, for the twisting of the chela is in itself a structural feature that is sigmalike; that is, the twisted chela is intermediate, in respect to the shape of the spicular axis, between the sigma and the normal chela, although in other respects it is a perfectly differentiated chela.
1921, W.C. George and H.V. Wilson, “Sponges of Beaufort (N.C.) Harbor and Vicinity”, in Bulletin of the United States Bureau of Fisheries, volume 36, page 150They predicted that there should be other sigmalike factors that would select other classes of promoters in response to the cell's needs.
