Determine the outcome for the lac operon genotype shownbelow:
IsP+OcZ+
Assume lactose is present.
Select one:
Functional beta-galactosidase is produced constitutively.
Functional beta-galactosidase is NOT produced.
Determine the outcome for the lac operon genotype shownbelow:
I-P+OcZ+
Assume lactose is present.
Select one:
Functional beta-galactosidase is produced constitutively.
Functional beta-galactosidase is NOT produced.
Mark all that are true about the lac operon.
Select one or more:
CAP and cAMP bind to increase transcription of structuralgenes.
RNA polymerase binding occurs best if CAP is present and cAMP isabsent.
The presence of glucose decreases CAP-cAMP binding to theoperon.
The presence of additional cAMP decreases CAP binding to theoperon.
DNA methylation may be a significant mode of genetic regulationin eukaryotes. Methylation in this case refers to...
Select one:
Addition of methyl groups to RNA polymerase
Addition of methyl groups to tRNA
Addition of methyl groups to DNA polymerase
Addition of methyl groups to cytosine
