1. code for repressor proteins
2. are not transcribed continuously
3. are not contained in the operon they control
4. All of the above
All of the above
1. usually involved in anabolic pathways
2. produced when a small molecule inactivates the repressor protein
3. produced when an activator molecule enhances the attachment of RNA polymerase with the operator
4. regulated by inherently inactive repressor molecules
produced when a small molecule inactivates the repressor protein
1. gene expression differentiates specialized cells
2. the chromosomes are linear and more numerous
3. operons are controlled by more than one promoter region
4. inhibitory or activating molecules may help to regulate transcription
gene expression differentiates specialized cells
1. They are RNA molecules that are not translated into proteins
2. They are DNA segments that lack promoter or other control region
3. They are not expressed-they do not produce a functional product
4. They appear to have arisen from retrotransposons
They are not expressed-they do not produce a functional product
1. Bundle sheath
2. Guard cells
3. Epidermal cells
4. Mesophyll calls
Mesophyll calls
1. When bound with activators, they interact with the promoter region and other transcription factors to increase the activity of a gene
2. They may complex with steroid activated receptor proteins and thus, selectively activate specific genes
3. They may coordinated the transcription of enzymes in the same metabolic pathway
4. They are located within the promoter and when complexed with a steroid or other small molecule they release an inhibitory protein and thus, make DNA more accessible to RNA polymerase
They are located within the promoter and when
complexed with a steroid or other small molecule
they release an inhibitory protein and thus, make
DNA more accessible to RNA polymerase
