Transcription and Regulation The binding of lac repressor to DNA could be considered to be analogous to mixed-type inhibition of an enzyme uncompetitive inhibition of an enzyme allosteric effects in enzyme regulation competitive inhibition of an enzyme mixed-type inhibition of an enzyme uncompetitive inhibition of an enzyme allosteric effects in enzyme regulation competitive inhibition of an enzyme ANSWER DOWNLOAD EXAMIANS APP
Transcription and Regulation The closed complex at bacterial promoters is not affected by promoter mutations bound more tightly when repressors are present not affected by activator proteins in equilibrium with free RNA polymerase and the promoter not affected by promoter mutations bound more tightly when repressors are present not affected by activator proteins in equilibrium with free RNA polymerase and the promoter ANSWER DOWNLOAD EXAMIANS APP
Transcription and Regulation Most transcripts of protein coding genes are cleaved at the 5' end immediately after a poly adenylation signal at the 5' end immediately before a poly adenylation signal at the 3' end just after a poly adenylation signal at the 3' end just before a poly adenylation signal at the 5' end immediately after a poly adenylation signal at the 5' end immediately before a poly adenylation signal at the 3' end just after a poly adenylation signal at the 3' end just before a poly adenylation signal ANSWER DOWNLOAD EXAMIANS APP
