Plant growth substances as modulators of transcription.

Abstract

In all living cells, the expression of genetic information involves the transcription of nucleotide sequences in DNA of the genes into nucleotide sequences in RNA molecules and the translation of these sequences in RNA into amino acid sequences in proteins. The process by which the information flows from DNA to RNA is termed transcription and that from RNA to protein is called translation. DNA-dependent RNA polymerase (ribonucleoside triphosphate RNA nucleotidyl transferase, E.C. 2.7.7.6) is the key enzyme implicated in the process of transcription. The interesting property of this enzyme is its binding to specific sites of the DNA template thus ensuring the proper initiation of the RNA chain, essential to produce a meaningful message. The regulation of transcription in prokaryotes has already been studied in detail (Burgess, 1971; Chamberlin, 1974a, b). In contrast, however, less progress has been made in the case of eukaryotes, seemingly due to the complexity in the genetic apparatus and the makeup of the eukaryotic cells (Jacob, 1973; Chambon, 1974, 1975; Biswas et al., 1975a; Duda, 1976).KeywordsGibberellic AcidPlant HormoneRibonucleic AcidNucleic Acid SynthesisPlant Growth SubstanceThese keywords were added by machine and not by the authors.
